New flex was one of things I wanted to push when I took over the maintenance of flex. But for the same reasons that are mentioned here [1] I didn't. I'll see if we can provide new flex as extras package, or something along these lines, so those more adventurous can see if it works. (The problem obviously is that flex is required for building, so mere installation doesn't show anything. You need to actually use it to build things, and vastly less people build with flex on fedora than just use it...) [1] https://www.redhat.com/archives/fedora-devel-list/2006-May/msg00077.html |
Description of problem: This is not really a bug report but more an update request. On FC5, I'm not able to compile the latest snapshots of MIPL (Mobility for IPv6) because they introduced in their lex file some directives that are not supported by the version of flex shipped in FC5: 2.5.4a (released in 1997). Those options are '%top{' and options 'noyyget_*' They are supported by flex 2.5.31 and above. After some googling I discovered that the flex state seems ambiguous as many distributions ship different versions of flex. Is there any plan to update the flex version shipped in fedora? Version-Release number of selected component (if applicable): 2.5.4a How reproducible: Always. Steps to Reproduce: 1. Download latest snapshot of MIPL from 2. autoreconf -i 3. ./configure (with the proper options) 4. make 5. flex scan.l "scan.l", line 28: unrecognized '%' directive ... "scan.l", line 48: unrecognized %option: yyget "scan.l", line 49: unrecognized %option: yyget ... Actual results: make fails. Error is: The following directives are not supported by flex 2.5.4a: %top{ %option noyyget_lineno noyyset_lineno %option noyyget_in noyyset_in %option noyyget_out noyyset_out %option noyyget_debug noyyset_debug %option noyyget_leng %option noyyget_text Expected results: make succeeds Additional info:
