Thanks David,

I'll stick to the --with-pthread option.

Rgds,

Michel

"lthread" and the "--with-linuxthreads" option was used exclusivily with the port of the "Linux threading library" that was commonly found on older releases of xBSD (FreeBSD in particular).  It has no relevance to GNU/Linux systems whatsoever, and in any case should be depreciated now that more recent xBSD kernels have fully native smp and thread support.

Hello,

I was compiling a package of Common C++ 1.3.12 when I noticed that a chmod fails during make install. Reason was the absence of a $(DESTDIR) in src/Makefile.am.

I've attached the patch if anyone's interested. the 'reconfig' script should be executed after applying.

Secondly,
I noticed that the configure script assumes that 'lthread' is the library used for LinuxThreads (--with-linuxthreads). On several Linux distributions I checked, the 'pthread' library is used for LinuxThreads instead.

A README file I found in the glibc Slackware 10.1 package (probably copied from the glibc source tree) in /usr/doc/glibc-2.3.4/linuxthreads/, states:

/USING LINUXTHREADS:

        gcc -D_REENTRANT ... -lpthread
/
Is this the same on all Linux distributions? It appears to be the case for RedHat 7.2 (glibc 2.2.4), Slackware 7.1.0 (glibc 2.1.3), Slackware 8.0.0 (glibc 2.2.3) and Slackware 10.1 (glibc 2.3.4).

In any case building --with-linuxthreads causes the build to fail because liblthread cannot be found.
Using --with-pthread=pthread at configure time instead of --with-linuxthreads fixes that problem, btw.

Cheers,

Michel Stam
