All,
I want to build a softphone using PJSIP on MAX OS X with MAC OS X UI.
NOTE: this is not about the iPhone SDK.
I first tried to create a build environment for PJSIP in Xcode and
found this to be significantly beyond my skill level. I was not simply
wanting to call out from Xcode to a make/makefile environment - can
use the latter directly. So, I simply built PJSIP with the usual
"configure/make dep/make" commands and satisfied myself that all was
working well using the sample applications.
Now I would like to use Xcode to build my application. I have created
a small project with the following code:
#define PJ_AUTOCONF 1
#include <stdio.h>
#include <pjlib.h>
int main (int argc, const char * argv[]) {
printf("\nHello PJSIP\n\n");
return 0;
}
Within Xcode, I'm getting two errors related to pj_jmp_buf stating
"error: syntax error before 'pj_jmp_buf'" in except.h (line 295) and
setjmp.h (line 30). There are also some warnings related to these
errors. I've attached the build results at the end of this message.
I'm not sure how to solve these errors or the warnings about "implicit
declarations".
When I follow the PJSIP instructions regarding GNU Make, I can build
the file without error and run it without problem.
Any suggestions or corrections would be appreciated.
Here are the build results from Xcode:
