FATE tests don't build when SDL is installed. (mingw/windows)

[Greg Wolfe]

Have the latest git on a Win7/32-bit system with MinGW-32/msys environment. Downloaded, built, and installed SDL. After successfully building ffmpeg, attempted to "make fate" and got the following error:

make fate SAMPLES=fate-suite/
CC      libavcodec/fft-test.o
<command-line>:0:6: error: no previous prototype for 'SDL_main' [-Werror=missing-prototypes]
c:/Data/ffmpeg/libavcodec/fft-test.c:243:5: note: in expansion of macro 'main'
 int main(int argc, char **argv)
     ^
cc1.exe: some warnings being treated as errors
make: *** [libavcodec/fft-test.o] Error 1

A little research showed this to be the same problem as described in ticket #256. Applied same change and the problem was resolved. However, the same problem exists in a number of source files. Here is the list of files to which I applied the change to get the FATE regression tests to build and run:

libavcodec/dct-test.c
libavcodec/fft-test.c
libavcodec/golomb-test.c
libavcodec/iirfilter.c

Maybe it would be easier to fix this in the Makefile?

in
library.mak, DTEST is added to build the tests
$(TESTOBJS) $(TESTOBJS:.o=.i): CPPFLAGS += -DTEST

please try to remove the -Dmain or add -Umain or someting there

[Greg Wolfe]

I tried adding -Umain to the specified line in library.mak and got the same error.

I emailed a while back with my current solution, but I guess I should have documented it here. The following "make" command line resolves the problem:

make fate SAMPLES=fate-suite/ CC_C="-c -Umain"

Tbe response to this was something like "ok, but it would be nice to have a solution that worked out of the box instead of having to use a custom make command line." I agree.

[Michael Niedermayer]

Is this issue still occuring ?
