Subject [jira] [Commented] (DAEMON-255) jsvc cannot find libcap.so on rhel
Date Thu, 16 Aug 2012 16:51:38 GMT

    [ https://issues.apache.org/jira/browse/DAEMON-255?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13436091#comment-13436091
] 

John Allison commented on DAEMON-255:
-------------------------------------

Yes, adding the 64 bit locations seems to have worked:
 {{
static const char *libcap_locs[] = {
    "/lib64/libcap.so.2",
    "/lib64/libcap.so.1",
    "/lib64/libcap.so",
    "/lib/libcap.so.2",
    "/lib/libcap.so.1",
    "/lib/libcap.so",
    "/usr/lib64/libcap.so.2",
    "/usr/lib64/libcap.so.1",
    "/usr/lib64/libcap.so",
    "/usr/lib/libcap.so.2",
    "/usr/lib/libcap.so.1",
    "/usr/lib/libcap.so",
    NULL
};
}}

> (formatting doesn't work: that's /usr/STAR/libcapSTAR in the ls)
> If I symlink {{/usr/lib/libcap.so -> /lib64/libcap.so}} then it starts and seems to
work fine. This did not happen in 1.0.7
> Following issue links from DAEMON-242 I tried rerunning autoconf locally. But there is
no -lcap anywhere and ldd doesn't show it.
> Perhaps you just need to add /lib64 into the dlopen loop?
