EE_INCS += -I$ ./INC
EE_LDFLAGS += -L$ ./LIB

Are you sure it isn't 'libjpeg.a' instead of 'libjpg.a'?
If so, you'd need a '-ljpeg'. |

<sincro> i try emoonwork
<emoonwork> ooPo: maybe no extern "C" {...} in the header for the C functions?
<ooPo> hmm, that's quite possible
<sincro> <emoonwork> with -lstdc++ i solve __gxx stuff problem
<ooPo> yup, no extern in the header
<sincro> but other undefined reference have problem
<sincro> i have past source code link on forum
<ooPo> http://cvs.ps2dev.org/libjpg/libjpg/include/libjpg.h?rev=1.3
<emoonwork> ok, no extern "C"
<ooPo> just put some around where it is included in his code
<emoonwork> yeah
<sincro> ?
<sincro> extern c in source?
<sincro> ok i try |
| Code: | #ifdef __cplusplus
extern "C" {
#endif
#include <libjpg.h>
#ifdef __cplusplus
}
#endif |
