Compiling libptrace

Trying to compile libptrace ( http://sourceforge.net/projects/libptrace/ ). The project did not advertise any preferred methods of requesting support (unfortunately, this project did not indicate the best way to get help). Anywho, the problem I am facing is as follows:

% ./build.sh
% ...[SUCCESS]
% ./configure
% ...[SUCCESS]
% make
Making all in src
make[2]: Entering directory `/home/xxx/build/libptrace-git.git/src'
make[2]: *** No rule to make target `../lib/libgnu.la', needed by `libptrace.la'.  Stop.
make[2]: Leaving directory `/home/xxx/build/libptrace-git.git/src'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/xxx/build/libptrace-git.git'
make: *** [all] Error 2
%

If you use google libptrace and libgnu.la, you get null images. The grapping for it in the source is taken from git, you get:

% grep -sre libgnu.la *
src/Makefile.in:libptrace_la_DEPENDENCIES = ../lib/libgnu.la
src/Makefile.in:libptrace_la_LIBADD = ../lib/libgnu.la
src/Makefile.am:libptrace_la_LIBADD = ../lib/libgnu.la
src/Makefile:libptrace_la_DEPENDENCIES = ../lib/libgnu.la
src/Makefile:libptrace_la_LIBADD = ../lib/libgnu.la

I do not know how to create the libtool archive file, and the source does not seem to have any goals or scripts for this.

Admin note: add the `libptrace 'tag to this question - obviously a very popular topic - I cannot do this because I do not agree with the point number 1.5K :(

First of all, it only works on Linux. If you want this to work on other systems, you will need to write the src / libptrace_config.h header in the configure.ac file, as you can see on grep COMPILE_HDR configure.ac.

Secondly, the next patch is all I need to get the point at which the generated header is missing on my system. Of course, gnulib must be installed, and the gnulib tool must be in $ PATH.
