warning working around a Linux kernel bug by creating a hole

[rkanavath]

patchelf --set-rpath /opt/lib /opt/lib/libQtCore.so.4.8.7
warning: working around a Linux kernel bug by creating a hole of 2088960 bytes in ‘/opt/lib//libQtCore.so.4.8.7’

I am using patchelf 0.9

I saw a related bug here: #47 and its fix f6886c2

But that didn't solved my issue.

size of libQtCore.so.4.8.7 is only 3.1 M

Was the result binary usable or you complained about the waning message?

Hi xiaosuo,

I am also facing similar issue for setting interpreter and rpath for libpthread.so.0, Warning message as shown below

• warning: working around a Linux kernel bug by creating a hole of 6976632 bytes in '/lib/libpthread.so.0'.

I would like to understand the significance of creating a hole of X bytes in the library.

Thanks in advance.

In fact, nothing bad will happen except for size bloating, because patchelf handles it for you. Just take it easy and ignore these warning messages.

I submitted a PR for these annoying messages.

See #111

Hi xiaosuo,

Thanks for the quick response.

I would like to know some additional information.

I am curious to know why the file bloating is required for dynamic libraries which is happening in the function rewriteSectionsLibrary().

Thanks in advance.

This appears to be obsolete, as the message is no longer present in current master (2a9cefd).

@xiaosuo Can this issue be closed also? As you mentioned, this is fixed by c4deb5e.

[xiaosuo]

Yes.

[sjackman]

Is it time to tag a stable release that includes c4deb5e?

[pratikpparikh]

Is this fixed?

[sjackman]

My understanding is that it's fixed in master in commit
c4deb5e but it's not yet fixed in a stable release.

Ubuntu 18.04 has 0.9 in the repositories but i still have the same issue

EDIT: And the executable isn't runnable anymore
