This is a trick about compiling Allegro programs that use #include <stdint.h>
I was getting the following errors: i586-pc-msdosdjgpp-gcc -Wall -O2 -g -fcommon -c -o src/bullet.o src/bullet.c In file included from /usr/local/djgpp/i586-pc-msdosdjgpp/sys-include/allegro/internal/alconfig.h:66, from /usr/local/djgpp/i586-pc-msdosdjgpp/sys-include/allegro/base.h:41, from /usr/local/djgpp/i586-pc-msdosdjgpp/sys-include/allegro.h:25, from src/bullet.c:1: /usr/local/djgpp/i586-pc-msdosdjgpp/sys-include/stdint.h:22:21: error: duplicate 'signed' 22 | typedef signed char int8_t; | ^~~~~~ /usr/local/djgpp/i586-pc-msdosdjgpp/sys-include/stdint.h:22:21: error: two or more data types in declaration specifiers 22 | typedef signed char int8_t; | ^~~~~~ /usr/local/djgpp/i586-pc-msdosdjgpp/sys-include/stdint.h:23:23: error: duplicate 'unsigned' 23 | typedef unsigned char uint8_t; | ^~~~~~~ /usr/local/djgpp/i586-pc-msdosdjgpp/sys-include/stdint.h:23:23: error: two or more data types in declaration specifiers 23 | typedef unsigned char uint8_t; | ^~~~~~~ /usr/local/djgpp/i586-pc-msdosdjgpp/sys-include/stdint.h:29:26: error: duplicate 'signed' 29 | typedef signed short int int16_t; | ^~~~~~~ /usr/local/djgpp/i586-pc-msdosdjgpp/sys-include/stdint.h:29:26: error: duplicate 'short' 29 | typedef signed short int int16_t; | ^~~~~~~ /usr/local/djgpp/i586-pc-msdosdjgpp/sys-include/stdint.h:30:28: error: duplicate 'unsigned' 30 | typedef unsigned short int uint16_t; | ^~~~~~~~ /usr/local/djgpp/i586-pc-msdosdjgpp/sys-include/stdint.h:30:28: error: duplicate 'short' 30 | typedef unsigned short int uint16_t; Depending a bit on the order of my #include. I discovered that if I add to CFLAGS: -DALLEGRO_HAVE_STDINT_H Then this problem goes away, becaue Allegro, rather than guessing types, would use #include , so definition are not made 2 times anymore causing theses errors. _______________________________________________ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
