 Posted: Mon 09 May '22 13:32 Post subject: Failed linking C shared library mod_md.so |
 |
|
This bug comes from at least version 2.4.48, but to the current version is still not fixed.
Before compiling Apache httpd-2, I have successfully compiled (also compile order) before using VS 2013 with Update 5 (Ultimate) + CMAKE v3.23.1 (x86_64): zlib v1.2.12, PCRE v8.45, Expat v2.4.8, OpenSSL v1.1.1o, libxml2 v2.9.14, jansson v2.14, Brotli v1.0.9, Lua v5.4.4, APR v1.7.0, APR-Util v1.6.1, Nghttp2 v1.47.0, cURL v7.83.0. All are the latest version!
With cURL, I compiled both dynamic libraries (before) and static libraries (after).
But when comes to Apache httpd-2 compile:

P/s: The error code above I copied from my previous error report on ASF Bugzilla – Bug 65602. The latest version is still the same.
During the HTTPD compilation, the compiler (apparently) didn't find cURL.
Previously, I have asked questions on StackOverflow about this error. No one has a solid solution, but they have come up with a "pretty good" solution: Compile again cURL during HTTPD compilation (i.e. cURL will be compiled a total of 3 times).
All relevant information will probably be on the report on ASF Bugzilla, I will add more information if missing. So I posted this topic in the hope that everyone could help me solve this error!
| Quote: | I don't understand the syntax of CMakeLists.txt (latest - v2.4.53), it seems to variable CURL_INCLUDE_DIR that exists but not SET.
Because JANSSON_INCLUDE_DIR variable, it appears 3 times, the first SET in the 97 line before being put into the SET in line 499.
Although I'm not sure, but CURL_INCLUDE_DIR has been created but has not been "assigned" so it couldn't find curl library... |

The CMAKE command line when compiling HTTPD is:
| Code: | | cmake -G "NMake Makefiles" -DCMAKE_INSTALL_PREFIX=\phpStudy\Apache -DCMAKE_BUILD_TYPE=Release -DENABLE_MODULES=i -DINSTALL_PDB=OFF .. |
Looking at your command line, it seems that you had to manually assign the entire path to the relevant folders and libraries?
Exactly is CMake was unable to automatically find the directory and the library of cURL? This is a bug of CMake, or of the CMakeLists.txt file of HTTPD?
I used because I skipped compiling APR-ICONV because I didn't know how to compile it using the CMake command line. So some modules like mod_charset_lite.so were not created.
P/s: Here are all my compiled command lines, can you take a look at it?! |

Looking on FindCURL.cmake:
| Code: | # Look for the header file.
find_path(CURL_INCLUDE_DIR
…
find_package_handle_standard_args(CURL
REQUIRED_VARS CURL_LIBRARY CURL_INCLUDE_DIR |
So, you MUST set CURL_LIBRARY & CURL_INCLUDE_DIR to have cmake be able to link it to httpd
Path might be relative or absolute
You ca have a look on my build files here: https://github.com/nono303/win-build-scripts/tree/master/modules |

Hello, I "guessed" the right problem.
First, I don't know the syntax used in CMake, so I will use the syntax in Java to explain.
The cause of the error is due to the CURL_INCLUDE_DIR and CURL_LIBRARIES variables which are declared but not have been initialized. That is why CMake has not been able to find the directory and library file of cURL.
I tried to change a bit, namely the value SET for CURL_INCLUDE_DIR and CURL_LIBRARIES variables inside the CMakeLists.txt file (please see the difference between the default version and the version I changed here). And praiseworthy, it found cURL and conducted normal compilation!
Anyway, I really hope they will update this change in the next version. |

Hi @tanquang,
I Clearly don’t understand what you mean with Java syntax or want to do patching CMakeLists.txt but… just simply change your cmd line from
| Code: | | cmake -G "NMake Makefiles" -DCMAKE_INSTALL_PREFIX=\phpStudy\Apache -DCMAKE_BUILD_TYPE=Release -DENABLE_MODULES=i -DINSTALL_PDB=OFF ... |
to
| Code: | | cmake -G "NMake Makefiles" -DCMAKE_INSTALL_PREFIX=\phpStudy\Apache -DCMAKE_BUILD_TYPE=Release -DENABLE_MODULES=i -DINSTALL_PDB=OFF -DCURL_LIBRARY=**YOUR_LIB_PATH**/libcurl.lib -DCURL_INCLUDE_DIR=**YOUR_INCLUDE_PATH**/ ... |
It might (must) works  |

| Yes. In fact both of you and I can help compile successfully. But I like something "more automatically". In my way, CMake can automatically find cURL that you don't need to manually specify the path to cURL. |

Hello
What is the cURL compilation command line that you are using?
I'm using these commands to compile cURL:
| Code: | ==================== Compile Dynamic Libraries ====================
cmake -G "NMake Makefiles" -DCMAKE_INSTALL_PREFIX=\phpStudy\Apache -DCMAKE_BUILD_TYPE=Release -DCURL_USE_OPENSSL=ON -DCURL_USE_SCHANNEL=ON -DCURL_WINDOWS_SSPI=ON -DCURL_BROTLI=ON -DUSE_NGHTTP2=ON -DHAVE_LDAP_SSL=ON -DENABLE_UNICODE=ON -DCURL_STATIC_CRT=OFF -DBUILD_SHARED_LIBS=ON ..
nmake
nmake install
==================== Compile Static Libraries ====================
cmake -G "NMake Makefiles" -DCMAKE_INSTALL_PREFIX=\phpStudy\Apache -DCMAKE_BUILD_TYPE=Release -DCURL_USE_OPENSSL=ON -DCURL_USE_SCHANNEL=ON -DCURL_WINDOWS_SSPI=ON -DCURL_BROTLI=ON -DUSE_NGHTTP2=ON -DHAVE_LDAP_SSL=ON -DENABLE_UNICODE=ON -DCURL_STATIC_CRT=OFF -DBUILD_SHARED_LIBS=OFF ..
nmake
nmake install |
I compiled cURL twice at the same time: First as dynamic libraries, then static libraries.
At this point, it will form two files: libcurl_imp.lib and libcurl.lib.
Then, if I specify -DCURL_LIBRARY as a libcurl.lib file just like you did during httpd compilation, I'll have the same error at the linking C shared library mod_md.so step. But if I specify -DCURL_LIBRARY is a libcurl_imp.lib file. It will compile normally without errors occurring.
Why is that? |

I have seen your curl build script. It can be seen, you are indicating -DBUILD_SHARED_LIBS as ON, but according to the library file you receive must be libcurl_imp.lib rather than libcurl.lib. Do you use a 3rd party curl library file?
I only received the file libcurl.lib after completing the Static Library compilation step (please see my compiled command line above). |

When building with a static libcurl (with VS16 or the like) there has to be an extra flag CURL_STATICLIB. Quoting my own remarks about mod_md:
| Quote: | NB. use libcurl_a.lib from curl schannel
perl -pi.bak -e "s/NDEBUG;WIN32/NDEBUG;CURL_STATICLIB;WIN32/gi" modules/md/mod_md.vcxproj
mod_md.dsp
/D "NDEBUG"
/D "NDEBUG" /D "CURL_STATICLIB" |

I have searched for documents related to the CURL_STATICLIB flag that you said. Incidentally, I found this article: CURL_STATICLIB + Visual Studio + CMake
So, you mean is that I need to change the cURL static library compiling command line to (I add it in front of the flag -DCURL_STATIC_CRT):
| Code: | | cmake -G "NMake Makefiles" -DCMAKE_INSTALL_PREFIX=\phpStudy\Apache -DCMAKE_BUILD_TYPE=Release -DCURL_USE_OPENSSL=ON -DCURL_USE_SCHANNEL=ON -DCURL_WINDOWS_SSPI=ON -DCURL_BROTLI=ON -DUSE_NGHTTP2=ON -DHAVE_LDAP_SSL=ON -DENABLE_UNICODE=ON -DCURL_STATICLIB=ON -DCURL_STATIC_CRT=OFF -DBUILD_SHARED_LIBS=OFF .. |
Then use the libcurl.lib file (instead of libcurl_imp.lib file) during the HTTPD compilation process? |

| Either use a shared libcurl without the flag or use a static libcurl with the CURL_STATICLIB flag. Both should work. |

So, with the dynamic library (libcurl_imp.lib file), I can build without any problems. But with the static library, I will have to use the CURL_STATICLIB flag (to use the libcurl.lib file) during the HTTPD compiler. |

I also confirmed the use of libcurl_imp.lib file (dynamic library) will work. I haven't tried on the static library (with CURL_STATICLIB flag) so I can't confirm ... |

Seems like something is not right for me...
I added the flag -DCURL_STATICLIB=ON when compiling the static cURL, specifically:
First, I will compile the dynamic library with the following commands:
| Code: | | cmake -G "NMake Makefiles" -DCMAKE_INSTALL_PREFIX=\phpStudy\Apache -DCMAKE_BUILD_TYPE=Release -DCURL_USE_OPENSSL=ON -DCURL_USE_SCHANNEL=ON -DCURL_WINDOWS_SSPI=ON -DCURL_BROTLI=ON -DUSE_NGHTTP2=ON -DHAVE_LDAP_SSL=ON -DENABLE_UNICODE=ON -DCURL_STATIC_CRT=OFF .. |
| Quote: | | P/s: According to cURL's CMakeLists.txt file, line 75, flag -DBUILD_SHARED_LIBS is set as ON by default. Therefore, I don't need to put that flag in the command line. |
After that, I proceeded to compile a static library with the following command line:
| Code: | | cmake -G "NMake Makefiles" -DCMAKE_INSTALL_PREFIX=\phpStudy\Apache -DCMAKE_BUILD_TYPE=Release -DCURL_USE_OPENSSL=ON -DCURL_USE_SCHANNEL=ON -DCURL_WINDOWS_SSPI=ON -DCURL_BROTLI=ON -DUSE_NGHTTP2=ON -DHAVE_LDAP_SSL=ON -DENABLE_UNICODE=ON -DCURL_STATICLIB=ON -DCURL_STATIC_CRT=OFF -DBUILD_SHARED_LIBS=OFF .. |
I have specified the flag -DCURL_STATICLIB as ON, this is what it printed:
| Quote: | -- curl version=[7.83.1]

(It seems) It is a warning related to Brotli, so I switched to Apache compilation.
Apache found a static library file (libcurl.lib file) but it still had the same error in the step [ 65%] Linking C shared library mod_md.so.
I don't understand why it still appears?! |
