How to solve -------undefined reference to `__chkstk_ms'-------on mingw

Solution 1:

Here's an authoritative answer, from a MinGW project administrator.

Your problem arises because you continue to use an obsolete, (no longer maintained; no longer supported), version of GCC. Current versions of mingwrt are compiled using GCC-4.x, (I used GCC-4.8.2 for mingwrt-3.21 and its descendants), and this introduces the dependencies on __chkstk_ms, (which is provided by libgcc -- a GCC-4.x specific library, which is incompatible with GCC-3.x).

FWIW, I can reproduce your issue if I install a GCC-4.8.2 built mingwrt-3.21.1 into a GCC-3.4.5 installation. By the same token, I can also successfully use mingwrt-3.21.1 with GCC-3.4.5, if I build it with that same version of GCC.

Thus, for an authoritative answer: if you must continue to use an obsolete GCC version, you need to be prepared to rebuild all associated libraries, using that same obsolete compiler.

Solution 2:

The orig problem seems solved regarding linking against old libs, but I have opposite case. I need to work with older GCC 3.4 version, so I installed gcc-v3-core package. Then orig errors immediately appear when linking a trivial source. I found out that MinGW GCC 3.4 cannot work with mingwrt > 3.20 and the problem is that gcc-v3-core contains incorrect mingwrt spec, allowing newest vesions.

The solution is simple:

mingw-get upgrade "mingwrt=3.20.*"

!Update! Actually with mingwrt-3.20 linker reports same errors for C++ code:

g++ hello.cpp

BAM!

Solution 2:

mingw-get upgrade "mingwrt=3.18.*"

the last one that seems to work with gcc-v3-g++.

Solution 3:

This might be a "modern" answer to the original question: You may miss the stdc++ and gcc library in MinGW, have to link them by yourself manually.
