Memo in building cernlib on Scientific Linux 7 (SL7) / CentOS 7  from EPEL6 cernlib-2006-35.el6.src.rpm

1. Assuinig OS is SL7 (or CentOS7)
{{{
# cat /etc/redhat-release 
Scientific Linux release 7.9 (Nitrogen)
}}}

2. Obtain cernlib-2006-35.el6.src.rpm from Fedora epel6 rep. and try rpmbuild
{{{
# mkdir rpm; cd rpm
# wget https://archives.fedoraproject.org/pub/archive/epel/6/SRPMS/Packages/c/cernlib-2006-35.el6.src.rpm or
# wget https://ftp.riken.jp/Linux/fedora-archive/fedora/epel/6/SRPMS/Packages/c/cernlib-2006-35.el6.src.rpm 
# md5sum cernlib-2006-35.el6.src.rpm
 d653276f5248b92ed20db78de3b21946  cernlib-2006-35.el6.src.rpm
# rpmbuild --rebuild  cernlib-2006-35.el6.src.rpm
}}}
will result
{{{
error: Failed build dependencies:
	lapack-devel is needed by cernlib-2006-35.el7.x86_64
	blas-devel is needed by cernlib-2006-35.el7.x86_64
	imake is needed by cernlib-2006-35.el7.x86_64
	xbae-devel is needed by cernlib-2006-35.el7.x86_64
}}}

3. Install needed dependencies

{{{
# yum install epel-release
# yum install lapack-devel blas-devel imake xbae-devel
}}}

Then, try rpmbuild again

{{{
# rpmbuild --rebuild  cernlib-2006-35.el6.src.rpm
}}}

After 25 minutes, process exam1 enters into infinite loop at the test of (G E A N T  Version 3.2114, RUN 1);

Abort rpmbuild by  CTRL-C .

4. Enter into the SPECS directory (cd ../rpmbuild/SPECS) and edit/modify cernlib.spec file
to remove geant321 from test_dirs

{{{
# diff cernlib.spec cernlib.spec.org
1190c1190
< test_dirs='graflib mclibs kernlib mathlib packlib phtools'
---
> test_dirs='graflib mclibs kernlib mathlib packlib phtools geant321'
}}}

5. rpmbuild again with the corrected spec. file
{{{
# rpmbuild -ba cernlib.spec
}}}

Build completes in 20 minutes.

NB. Since geant321 has problem in exam1(test), it is suggested not to install geant321-2006-35.el7.x86_64.rpm.
Newer version geant4 is available now.

(Thanks to Tetsuya Ohnish for information and suggestions.)
