[PURRS-devel] Building the PURRS infrastructure

[Andrea Pescetti]

The latest library versions can cause problems when trying to build the
PURSS infrastructure.

1) GiNaC
   GiNaC 1.3.7 works and is now on our FTP site.
   ftp://ftp.cs.unipr.it/pub/infrastructure
   GiNaC 1.3.6 apparently doesn't work due to a parsing problem.
   GiNaC 1.4.x (the current series) should work but we need to modify
   our configuration script in order to take into account
   http://www.ginac.de/pipermail/ginac-devel/2007-March/001167.html
   which dropped ginac-config for pkg-config.
   Our configure script and test program should not locate/execute
   ginac-config (which has been removed in 1.4.x) but
   pkg-config --modversion ginac
   (if you receive an error, just set PKG_CONFIG_PATH appropriately:
   PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/:$PKG_CONFIG_PATH
   if GiNaC is in /usr/local/lib ).
   Note: GiNaC is now dependent on pkg-config, but this shouldn't be
   a major problem.

2) GIAC
   GIAC 0.7.1 does not build without a patch we already happened to
   have to apply. The patch, suggested by Roberto, is under this
   message and a patched version og GIAC 0.7.1 is on our FTP site.

3) CGICC
   CGICC 3.2.4 (the latest version) apparently has changed its
   build scripts.
   Since this is not a key component, we can continue using
   CGICC 3.2.3, which is on our FTP site too.

Yours,
  Andrea.

Patch for GIAC 0.7.1:
