cgdb 0.6.4 Build failure

[nacho319@…]

It seems that cgdb's build flags choose the wrong OS for curses compatibility, leading to a compile error:

Making all in various
Making all in util
Making all in src
if gcc -DHAVE_CONFIG_H -I. -I. -I../../..   -I/opt/local/include -I./../include -O2 -MT pseudo.o -MD -MP -MF ".deps/pseudo.Tpo" -c -o pseudo.o pseudo.c; \
	then mv -f ".deps/pseudo.Tpo" ".deps/pseudo.Po"; else rm -f ".deps/pseudo.Tpo"; exit 1; fi
pseudo.c: In function ‘pty_open’:
pseudo.c:338: error: ‘I_PUSH’ undeclared (first use in this function)
pseudo.c:338: error: (Each undeclared identifier is reported only once
pseudo.c:338: error: for each function it appears in.)
pseudo.c: At top level:
pseudo.c:736: fatal error: opening dependency file .deps/pseudo.Tpo: Permission denied
compilation terminated.
make[4]: *** [pseudo.o] Error 1

which corresponds to this snippet of code for cgdb getting a pseudo tty I believe:

	/* Turn the slave into a terminal */

#ifndef HAVE_CYGWIN 
#ifndef HAVE_LINUX /* linux does not use the streams module */
	/*
	 * Push the appropriate streams modules, as described in Solaris pts(7).
	 * HP-UX pts(7) doesn't have ttcompat module.
	 */
	if (ioctl(*slavefd, I_PUSH, "ptem") == -1)
	{
		close(*masterfd);
		close(*slavefd);
		return -1;
	}

	if (ioctl(*slavefd, I_PUSH, "ldterm") == -1)
	{
		close(*masterfd);
		close(*slavefd);
		return -1;
	}

#ifndef __hpux
	if (ioctl(*slavefd, I_PUSH, "ttcompat") == -1)
	{
		close(*masterfd);
		close(*slavefd);
		return -1;
	}
#endif
#endif
#endif

Assigning to maintainer.

Adding the cgdb maintainers so we might get some action on this ticket and get it working for OSX.

Maybe the configure options can be adapted to avoid this build error.

Quick hack to get it to compile

[jauricchio@…]

Here's a simple patch to kludge around the code the original reporter mentioned. Compiles and launches. Not tested yet; I'm new to cgdb but if I encounter tty-related bugs or oddness, I'll see if they're caused by my changes and report back here.

This code is from ​libslack, not cgdb proper. There has been a new release of libslack, and it claims to support OS X. A good fix would be a patch to bring cgdb in line with whatever libslack does to build on OS X. A better fix would be getting upstream cgdb to update their libslack.

Maintainer timeout.

Committed revision r52098. Now it compiles and runs. Thanks!
