[EPEL-devel] Version of gcc in EPEL7

Hi, last week I have compiled the first alpha release of LyX 2.4 in copr. As I have been doing in other cases I have built the package in EPEL 7 and 8, together with the supported Fedora versions and rawhide. The code only failed in EPEL 7. In a sense this was to be expected since the code requires at least gcc 4.9 (full C++ support for regex is the culprit here). The reason why I am writing this is because there is a test in the autotools base to catch older versions of gcc and for some reason it is not working. I have been asked what is the output of g++ -dumpversion and g++ -dumpfullversion in EPEL. Could anyone that has an available installation send me that output, please? The other tangential question is if there is a newer gcc version that can be used in EPEL7. I think this question has been answered several times in this list but my search-fu is not working at the moment. What I wrote above only applies to EPEL 7 as EPEL 8 is working perfectly and I have recently released the stable version of LyX there. Best regards, -- José Abílio
