Topic: Compile session mod on Apache 2.4.43 dllimport not allowed

[Apache_clan]

Build info: windows 64, visual studio 2019 developer tool. Cmake, nmake

I was able to compile about 20 modules as part of libhttpd.dll by tweaking the original CMakeLists.txt
and modules.c, but I am not successful on compiling session module.

In CMakeList.txt:
SET(LIBHTTPD_SOURCES
${extra_builtin_modules}
${PROJECT_BINARY_DIR}/modules.c
modules/session/mod_session.c

In modules.c
extern module session_module;
and included to 3 declaration functions.


My cmake:
cmake -G "NMake Makefiles" -DCMAKE_INSTALL_PREFIX=./Release/x64 -DCMAKE_BUILD_TYPE=Release -DINSTALL_MANUAL=OFF -DINSTALL_PDB=OFF -DINSTALL_MANUAL=OFF -DEXTRA_INCLUDES=C:/OpenSSL-Win64/include ../src/httpd-2.4.43

nmake error:
E:\Dev\src\httpd-2.4.43\modules\session\mod_session.c(44): error C2491: 'ap_hook_session_load': definition of dllimport function not allowed
E:\Dev\src\httpd-2.4.43\modules\session\mod_session.c(44): error C2491: 'ap_hook_get_session_load': definition of dllimport function not allowed

Checking mod_session.c that error refers to this code:
APR_IMPLEMENT_EXTERNAL_HOOK_RUN_FIRST(ap, SESSION, int, session_load,
(request_rec * r, session_rec ** z), (r, z), DECLINED);
APR_IMPLEMENT_EXTERNAL_HOOK_RUN_FIRST(ap, SESSION, int, session_save,
(request_rec * r, session_rec * z), (r, z), DECLINED);
APR_IMPLEMENT_EXTERNAL_HOOK_RUN_ALL(ap, SESSION, int, session_encode,
(request_rec * r, session_rec * z), (r, z), OK, DECLINED);
APR_IMPLEMENT_EXTERNAL_HOOK_RUN_ALL(ap, SESSION, int, session_decode,
(request_rec * r, session_rec * z), (r, z), OK, DECLINED);

I am not sure how to fix this error. I am researching about dllimport and dllexport but I have no idea how to fix this.

I am not an expert in programming or compiling. I hope someone can shine some light on this error.

The makefile is such a pain to work with, causing so many errors, like parsing includes and switching between dllexport and dllimport.

See my final build.

Please post your working cmake file.

Why all modules static and not shared?
