Hi,I have modified the jccolor.c file of the jpeg-6a application.I have converted the file to assembler with :
sslittle-na-sstrix-gcc -O2 jccolor.c -S
Then I have replace some code with my mmx code in the function : rgb_ycc_convert.
Now I'm trying to recompile the whole application inserting the jccolor.s file but I don´t know how.

Can somebody tell me how can I compile the whole application inserting my modification
Thank you.

gcc file1.c file2.s -o myapp

gcc will treat a .s file as input, just like a .c or .o file. Is that what you mean?

The exact problem is :
I have modified the Makefile with :

CC= /home/martin/workspace/bin/sslittle-na-sstrix-gcc -O2 -I/usr/openwin/include -I/home/workspace/simple/sslittle-na-sstrix/include -I/home/workspace/simple/lib/gcc-lib/sslittle-na-sstrix/2.7.2.3 -I.

AR2= /home/martin/workspace/bin/sslittle-na-sstrix-ranlib

jcsample.o jchuff.o jcphuff.o jcdctmgr.o jfdctfst.o jfdctflt.o \
jfdctint.o

where jccolormartin_mmx_m.s is the file I have changed.

When I execute the Makefile this error appears :

/home/martin/workspace/bin/sslittle-na-sstrix-gcc -O2 -I/usr/openwin/include -I/home/workspace/simple/sslittle-na-sstrix/include -I/home/workspace/simple/lib/gcc-lib/sslittle-na-sstrix/2.7.2.3 -I. -o cjpeg cjpeg.o rdppm.o rdgif.o rdtarga.o rdrle.o rdbmp.o rdswitch.o cdjpeg.o libjpeg.a
libjpeg.a(jcinit.o): In function `jinit_compress_master':
jcinit.c:31: undefined reference to `jinit_color_converter'
make: *** [cjpeg] Error 1

How can I fix it?
