Bugzilla Bug 174576

ginac-137 configure problem with cln on 2 machines:

(...)
checking for cln-config... /usr/bin/cln-config
checking for CLN - version >= 1.1.0... no
*** Could not run CLN test program, checking why...
*** The test program compiled, but did not run. This usually means
*** that the run-time linker is not finding CLN or finding the wrong
*** version of CLN. If it is not finding CLN, you'll need to set your
*** LD_LIBRARY_PATH environment variable, or edit /etc/ld.so.conf to point
*** to the installed location. Also, make sure you have run ldconfig if that
*** is required on your system
(...)
**** The following problems have been detected by configure.
**** Please check the messages below before running "make".
**** (see the section 'Common Problems' in the INSTALL file)

** No suitable installed version of CLN could be found.

I've checked cln-config:
# cln-config --version --cppflags --libs
1.1.13

-L/usr/lib -lcln -lgmp

emerge --info on first machine and second machines in attachmment

Hi Bartosz,

Could you please post your config.log so I can see why configure
is failing at detecting cln.

Thanks,
Markus

Thanks! It looks like you are getting a segmentation
fault during the configure step on both machines.
Could you please replace '-Os' with '-O2' and try
again. 

Thanks,
Markus

Hi, I've reemerged both: cln and ginac with -O2 flag. It works ;). Thank you !
Cheers

Great :) I'll see if I can reproduce this on my machine and 
may filter -Os should this be the case.

Thanks,
Markus

The cln-1.1.13 ebuild now filters -Os since it leads
to segmentation faults on both of my dev boxes as well.

Thanks,
Markus

hi,
I am on a powerpc G4 machine

/etc/make.conf
  CFLAGS="-O2 -mcpu=G4 -mtune=G4 -maltivec -mabi=altivec -fno-strict-aliasing
-pipe"

I emerged  sci-mathematics/ginac-1.3.7

and I had issu with cln.1.2.2 while I had no issue with cln-1.1.13


also cln-1.1.13 has /usr/bin/cln-config, while cln-1.2.2 has not

does it mean shouldn't I update the cln to the 1.2.2. ?

regards
