Bug ID: 382083
Summary: Failure to detect MUSL consistently.
Product: valgrind
Version: 3.13.0
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: jsew...@acm.org
Reporter: i1243...@mvrht.net
Target Milestone: ---
On some platforms (tested on the following), Valgrind 3.13.0 will fail to
configure/compile/link against the MUSL 1.1.16 library. Other versions have not
been tested, though other versions may also be affected.
MUSL provides a GCC wrapper called 'musl-gcc' which loads a GCC '.conf' file on
top of the system GCC, though these changes are not actually printed when the
'-dumpversion' flag is used. This flag is used to test whether MUSL is being
used; and in this case, the configure script(s) fail to detect MUSL and die
with an error about not having glibc >= 2.2.
A simple workaround is provided below, following the steps to replicate the
issue.
$ uname -a
Linux hostname 3.10.0-514.21.1.el7.x86_64 #1 SMP Thu May 25 17:04:51 UTC 2017
x86_64 x86_64 x86_64 GNU/Linux
$ gcc --version
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-11)
(1) Compile and install MUSL 1.1.16:
$ wget http://www.musl-libc.org/releases/musl-1.1.16.tar.gz
$ tar -xf musl-1.1.16.tar.gz
$ cd musl-1.1.16
$ ./configure --prefix=$HOME/musl --disable-shared
$ make -j`nproc` install
(2) Attempt to compile Valgrind 3.13.0:
$ wget ftp://sourceware.org/pub/valgrind/valgrind-3.13.0.tar.bz2
$ tar -xjf valgrind-3.13.0.tar.bz2
$ cd valgrind-3.13.0
$ CC=$HOME/musl/bin/musl-gcc \
./configure --prefix=$HOME/valgrind
(3) Observe that it prints the following, then exits:
configure: error: Valgrind requires glibc version 2.2 or later, uClibc,
(4) To remedy the issue, run:
$ sed -e 's@-dumpmachine |@-v |\&@' -i configure* # gets .ac too
$ CC=$HOME/musl/bin/musl-gcc \
./configure --prefix=$HOME/valgrind
$ make -j`nproc` install
(5) Observe that Valgrind is successfully configured, compiled, installed.
