Latest Cygwin (as of 3/13/2003) on Windows 98 SE.
>Description:
Trying to compile wxWindows 2.4.0 on Win98SE with Cygwin's latest gcc.
I did "configure", "make" and the compile line below fails.
Here is the error message:
src/png/pngread.c: In function `png_read_info':
src/png/pngread.c:509: internal error: Illegal instruction
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
make: *** [pngread.o] Error 1
I attach pngread.i.
I must admit, Win98SE is not a very stable development platform, so it might just be something wild unrelated to gcc. On the other hand, I've tried rebooting several times, and this file just cannot be compiled by me.
>How-To-Repeat:
The compile line that fails:
gcc -c -I./lib/wx/include/msw-2.4 -I./include -I./src/png -D_WIN32_IE=0x400 -D__WIN95__ -D__WXMSW__ -DWXUSINGDLL=1 -fno-pcc-struct-return -O2 -MMD -Wall -UWXUSINGDLL -DWXMAKINGDLL=1 -D_DLL=1 -D_WINDLL=1 -o pngread.o ./src/png/pngread.c
