Distributed Lib - ABI Mismatch Topic is solved

[saifcoder]

Our customers use our product developed in wx3.1/C++, On part of our product must be compiled every time the customer use it, its a small C++ file.

The problem is the wx3.1 lib distributed to our customers compiled by GCC 6.0, but the same customers have GCC 7 / 8 now.. then the recompiling of the small C++ file fail in linking stage, due a ABI mismatch

Code: Select all

The library used 3.1.1 with C++ ABI 1002
and your program used 3.1.1 with C++ ABI 1011 / 1012..

So, what is the best solutions ?

1 - Recompiling wx3.1 lib by GCC 8, then re-distribute to all customers.
2 - Compiling the small C++ file with old ABI.. D_GLIBCXX_USE_CXX11_ABI=0

If we use solution 1, whats will happen to customers that have GCC 5, 6, 7, when they use lib compiled by gcc 8 ?

Thank you,

PS: This is not duplicated post, in this situation, the lib is distributed to different users, and need to re-compiling a small C++ file before linking with the lib.

Thank you,

The best solution is probably a 3rd: update the library code to latest master or patch it with the relevant change only.
It was recently addressed by relaxing that check because of g++7 ABI changes.

Your solution work fine,
Thank you catalin,
