Showing man page fails when info not found #12
Comments
|
I came here to report the same issue... the point is that some implementations of man (ie man-db, used by most distros) have a non-standard "-W" option, others (in my case, mandoc on voidlinux) do not. snprintf(buf, sizeof(buf), "man -w -W %s %s", ManOptions, name);
pathFile = popen(buf, "r");
if (fgets(buf, sizeof(buf), pathFile)==NULL)
{
/* Try without -W */
snprintf(buf, sizeof(buf), "man -w -W %s %s", ManOptions, name);
pathFile = popen(buf, "r");
if (fgets(buf, sizeof(buf), pathFile)==NULL)
{
fprintf(stderr, "Error executing command '%s'\n", buf);
exit(1);
}
}
pclose(pathFile);Should have no functional change as "-W" shows catpages which are no longer widespread afaik. |

I've run into this same issue on both NixOS and Void Linux. (it worked fine on Arch) I'm going to try building from source with this patch to see if it fixes it. |

The call to the man program has man -W and there is no option for man -W causing an error.
In manual.c at line 185 looks like the problem:
snprintf(buf, sizeof(buf), "man -w -W %s %s", ManOptions, name);Maybe -C for configuration. This is a problem when the info page is not found.
