|Subject:||Potential bug with my --synclines|
|Date:||Thu, 6 Jun 2019 19:47:50 +0000|
I am running into an issue with m4 synclines. I have a list of m4 files which point to child m4 files. This reaches a hierarchy level of 12. When I write out a list of these m4 files and one at a time read them with m4 synclines I am able to read them without an issue. When I put this into a recursive loop at some point m4 synclines stops returning any value. The return code does show that an error is occurring, but I cannot determine what the issue is. I have tried the different –debug options, and have had no luck.
In the recursive function I am getting a list of all included m4 files at the current level, writing them to a file, and then closing that file. Once the file is closed, I recursively call the function on the new list of m4 files. I am using perl `m4 –synclines $infile > $output`.
The version of m4 I am using is 1.4.13. I am running on RHEL6.
Is this a known issue?
