It seems like MATLAB is royally screwed up on Linux, because it "dynamically loads some libs with static TLS", which doesn't mean anything to me other than I get bunches of errors.
The suggested work around is to rebuild glibc
with a larger DTV_SURPLUS
. This leaves me with two questions:
- How do I rebuild
glibc
on Arch Linux to increase theDTV_SURPLUS
? I looked at the PKGBUILD in the abs tree and didn't seeDTV_SURPLUS
anywhere, so I don't know where to make the change. - What value do I set
DTV_SURPLUS
to be? Presumably, setting it to
2^64
would both be overkill and a bad idea.
The issue with MATLAB can be seen with the following MWE in R2014a:
>> ones(10)*ones(10);
>> doc('help');

Where ones(10)*ones(10);
loads the dynamically linked libiomp5.so
BLAS library, which seems to not leave enough space for the dynamically linked libxul.so
required for the HTML based documentation browser. Potentially I can work around this particular MWE by using a patched version of libiomp5.so
, but the general problem still persists.
Best Answer
To recompile glibc with custom
DTV_SURPLUS
and override the existing version:/var/abs/core/glibc
to another directory so you can write to it without being root, thencd
to that directory.makepkg -o
to download and extract the source code without building it(because we will edit the source code before building).DTV_SURPLUS
located insrc/glibc-<version>/sysdeps/generic/ldsodefs.h
. You may just change the number in the line containingDTV_SURPLUS
.makepkg -e
.sudo pacman -U <package file>
. This will override the official package previously installed.If you don't want to override the existing version, you can use chroot, or maybe LD_PRELOAD will also work.
However, I'm unsure what should
DTV_SURPLUS
be.
