Opening a project ignores duplicated linker options

[Mr_KoKa]

When opening a project with target like this (please notice duplicated -lcrypto and -lssl)

Code Select Expand


<Target title="Release">
<Option output="bin/Release/Project" prefix_auto="1" extension_auto="1" />
<Option object_output="obj/Release/" />
<Option type="0" />
<Option compiler="msys2_mingw32" />
<Compiler>
<Add option="-O2" />
<Add option="-Wextra" />
<Add option="-std=c++11" />
<Add option="-Wno-unused-parameter" />
<Add option="-DCURL_STATICLIB" />
<Add directory="C:/curl-7.88.1/include" />
<Add directory="include" />
</Compiler>
<Linker>
<Add option="-s" />
<Add option="-static" />
<Add option="c:\curl-7.88.1\lib\.libs\libcurl.a" />
<Add option="-DCURL_STATICLIB" />
<Add option="-lgdiplus" />
<Add option="-lcomctl32" />
<Add option="-lgdi32" />
<Add option="-lbcrypt" />
<Add option="-lcrypto" />
<Add option="-lssl" />
<Add option="-lcrypto" />
<Add option="-lssl" />
<Add option="-lzstd" />
<Add option="-lz" />
<Add option="-lwldap32" />
<Add option="-lcrypt32" />
<Add option="-lws2_32" />
</Linker>
</Target>


Result is:



So the duplicated linked options are ignored. Project does not compile without them.

I would suggest putting the libraries in the link library list and see if that works.

It does not work either. After opening project with target linker section as such:

Code Select Expand


<Linker>
<Add option="-s" />
<Add option="-static" />
<Add library="c:/curl-7.88.1/lib/.libs/libcurl.a" />
<Add library="libgdiplus.a" />
<Add library="libcomctl32.a" />
<Add library="libgdi32.a" />
<Add library="libbcrypt.a" />
<Add library="libcrypto.a" />
<Add library="libssl.a" />
<Add library="libzstd.a" />
<Add library="libz.a" />
<Add library="libwldap32.a" />
<Add library="libcrypt32.a" />
<Add library="libws2_32.a" />
<Add library="libcrypto.a" />
<Add library="libssl.a" />
<Add directory="C:/msys64/mingw32/lib" />
</Linker>

Result is:


It works until restart.

But as I wrote this post I thought about solution to mklink these 2 libraries I need duplicated to different location and add them full path second time and it works, does not remove as duplicate.

The linker section look now like this:

Code Select Expand


<Linker>
<Add option="-s" />
<Add option="-static" />
<Add library="c:/curl-7.88.1/lib/.libs/libcurl.a" />
<Add library="libgdiplus.a" />
<Add library="libmsimg32.a" />
<Add library="libbcrypt.a" />
<Add library="libcrypto.a" />
<Add library="libssl.a" />
<Add library="C:/libdup/libcrypto.a" />
<Add library="C:/libdup/libssl.a" />
<Add library="libzstd.a" />
<Add library="libz.a" />
<Add library="libwldap32.a" />
<Add library="libcrypt32.a" />
<Add library="libws2_32.a" />
<Add directory="C:/msys64/mingw32/lib" />
</Linker>


BTW when adding library path to linker search path and entering them by filename without full path they become linker options instead in build log, only libraries added by full path appear as files in build log, so maybe adding them all as full path would work, or maybe it would still be seen as duplicate and would be removed.

-s -static  -lgdi32 -luser32 -lkernel32 -lcomctl32 c:\curl-7.88.1\lib\.libs\libcurl.a -lgdiplus -lmsimg32 -lbcrypt -lcrypto -lssl C:\libdup\libcrypto.a C:\libdup\libssl.a -lzstd -lz -lwldap32 -lcrypt32 -lws2_32 -mwindows


Thanks for the idea for the workaround :]

Example: gdiplus should be added to linker library list if you wish to link to shared gdiplus.
If you wish to link to static library then use full library paths work for me.

Edit: IIRC, using "libgdiplus.a" tells the compiler to link to static version of gdiplus for some Compilers.
