Linking with -static-libstdc++ flag on MinGW 4.7.1

Question

I try to compile with Allegro 5 on MinGW 4.7.1 using Code::Blocks 12.11 on Windows 7 with these compiler flags (In Project > Linker settings > Other linker settings):

-static-libgcc  
-static-libstdc++

Result:

unrecognized command line option '-static-libstdc++'

How to solve it?

This is surely not off-topic IMHO. I think that code compilation issues/errors given by a C++ compiler is on-topic. — Victor Stafusa - BozoNaCadeia, May 13 '16 at 14:51

What does g++ --version say? I don't know the exact version when it was introduced, but -static-libstdc++ is a fairly recent addition. Before, you had to do something like -static -lstdc++ -dynamic. (If the compiler version is 4.7.1, this should not be a problem, but I don't know how MinGW versions map to the actual compiler version.)

Wow, it says 4.6.2. I was sure it is 4.7.1. since there is mingw32-gcc-4.7.1.exe in distributive. – topright gamedev Jan 08 '13 at 23:37

There is also a directory gcc\mingw32\4.7.1 in the distributive. What a chaos. – topright gamedev Jan 08 '13 at 23:56

@toprightgamedev IIRC (it's been a while since I've installed MingW---my current PC is Linux), there are several versions you can choose from on the download page. But the surest statement, in this regard, is what `g++ --version` says, since it is compiled in. But as another poster said: find where the libraries are located, and see if there is a `libstdc++.a` present. If not, download one. And make sure it is in the same directory; if g++ finds a `libstdc++.so` in an earlier directory, it won't look any further. – James Kanze Jan 09 '13 at 00:34

I've set explicit path to `libstdc++.a` and compile with the only "Other linker options": `-static-libgcc`. It says: `undefined reference to `_Unwind_Resume'` and `undefined reference to `__gxx_personality_v0' ` – topright gamedev Jan 09 '13 at 00:45
This can also happen when using mingw with `-static-libgcc -static-libstdc++` linker flags. Read more here: https://stackoverflow.com/questions/50779224/exceptions-not-caught-when-linking-static-libs – vgulkevic Oct 25 '20 at 18:15

I have not tested but try to separate as -static -libstdc++

"cannot find -libstdc++" – topright gamedev Jan 08 '13 at 22:33
there is libstdc++.a in MinGW/lib/gcc/mingw32 – topright gamedev Jan 08 '13 at 22:33

@toprightgamedev That's a good question. If there's no static library present, g++ can't link with it. (If there isn't, it's a bit silly, because I can't think of any case where you'd want to link the c++ standard library dynamicallyl) – James Kanze Jan 08 '13 at 23:12
Yes, MinGW 4.7.1 (that was installed with Code::Blocks 12.11) has only libstdc++.a (searched by `libstdc`) – topright gamedev Jan 08 '13 at 23:30
I wanted to ask about it on Code::Blocks forums, but still waiting registration approval from admin... :] – topright gamedev Jan 08 '13 at 23:31

Replace "-libstdc++" with "lstdc++" I would think... – While-E Feb 12 '18 at 18:02
