[Debichem-devel] Bug#1096588: espresso: ftbfs with GCC-15

[Matthias Klose]

Package: src:espresso
Version: 6.7-3
Severity: important
Tags: sid forky
User: debian-gcc at lists.debian.org
Usertags: ftbfs-gcc-15

[This bug is NOT targeted to the upcoming trixie release]

Please keep this issue open in the bug tracker for the package it
was filed for.  If a fix in another package is required, please
file a bug for the other package (or clone), and add a block in this
package. Please keep the issue open until the package can be built in
a follow-up test rebuild.

The package fails to build in a test rebuild on at least amd64 with
gcc-15/g++-15, but succeeds to build with gcc-14/g++-14. The
severity of this report will be raised before the forky release.

The full build log can be found at:
http://qa-logs.debian.net/2025/02/16/amd64exp/espresso_6.7-3_unstable_gccexp.log.gz
The last lines of the build log are at the end of this report.

To build with GCC 15, either set CC=gcc-15 CXX=g++-15 explicitly,
or install the gcc, g++, gfortran, ... packages from experimental.

  apt-get -t=experimental install g++ 

GCC 15 now defaults to the C23/C++23 standards, exposing many FTBFS.
Other Common build failures are new warnings resulting in build failures
with -Werror turned on, or new/dropped symbols in Debian symbols files.
For other C/C++ related build failures see the porting guide at
http://gcc.gnu.org/gcc-15/porting_to.html

--------------------------------------------------------------------
ESPRESSO can take advantage of several optimized numerical libraries
(essl, fftw, mkl...).  This configure script attempts to find them,
but may fail if they have been installed in non-standard locations.
If a required library is not found, the local copy will be compiled.

The following libraries have been found:
  BLAS_LIBS= -lblas 
  LAPACK_LIBS=-L/usr/local/lib -llapack  -lblas 
  SCALAPACK_LIBS=-lscalapack-openmpi
  FFT_LIBS= -lfftw3 
  
  

Please check if this is what you expect.

If any libraries are missing, you may specify a list of directories
to search and retry, as follows:
  ./configure LIBDIRS="list of directories, separated by spaces"

Parallel environment detected successfully.\
Configured for compilation of parallel executables.

For more info, read the ESPRESSO User's Guide (Doc/users-guide.tex).
