Question on building for mingw64 32-bit with conflicting definition of SSIZE_T #2051

Open e-tmplr opened 5 days ago

e-tmplr commented 5 days ago

I'm trying to build the library for Windows 32-bit using mingw64 and conan, but I run into conflict with SSIZE_T.

Is this an issue with the library, or should I configure my toolchain differently, i.e. pass some flags?

I found a similar issue here: https://github.com/uclouvain/openjpeg/issues/1118 Solved in the library: https://github.com/uclouvain/openjpeg/pull/1119

Please advise.
