Read the release notes -- there is mention of GCC in there. Specifically, you will get into problems if you don't use the -fwritable-strings option of GCC. If you don't use it, then you are likely to get core dumps at random times when the I4GL libraries try to modify what turns out to be a string literal, which GCC carefully placed in the code (text) segment instead of the data segment, because Unix carefully ensures that you cannot modify anything in the code segment (shared text and all that). >What is Informix's position on GCC and will they support the >applications compiled with GCC? GCC? What's that? No, it probably won't officially be supported. Yes, it will actually work provided you use the option mentioned above.
