Introduction to Compface

Compface provides utilities and a library to convert from/to X-Face format, a 48x48 bitmap format used to carry thumbnails of email authors in a mail header.

This package is known to build and work properly using an LFS 12.2 platform.

Package Information

Installation of Compface

First, fix the configure script so that it's C99 compatible: 

autoreconf

Next, fix a build failure that occurs with GCC 14: 

sed -e '/compface.h/a #include <unistd.h>' \
    -i cmain.c                             \
    -i uncmain.c

Install Compface by running the following commands: 

./configure --prefix=/usr --mandir=/usr/share/man &&
make

This package does not come with a test suite.

Now, as the root user: 

make install &&
install -m755 -v xbm2xface.pl /usr/bin
