Title: uintptr_t (cross-compilation)
Post by: p.r. on January 17, 2009, 06:05:26 PM

I have cross-compilation error with aMule-2.2.3 source code.
But I had no errors with aMule-2.2.2 source code, the problem occurs only with aMule-2.2.3 source code.

I can't understand why "uintptr_t" is undeclared.
I have no knowledge of C/CPP
Please help.

Linux kernel 2.4.21-pre4
uClibc 0.9.26
GCC-3.3.3

Could you please try to include stdint.h in the file Format.cpp (add #include <stdint.h> where the other includes are) and see if it works then?

Thank you, it works.
Simple insertion of

Code: [Select]

#include <stdint.h> into Format.cpp has corrected the error:

There was no need to add stdint.h with full path.

Thanks a lot for this report, this problem will not occur with the next version of aMule. :)
