version GLIBCXX_3.4.21 not defined in file libstdc++.so.6 with link time reference

Also opened an issue on the libpd/abl_link repo: libpd/abl_link#13
The folks there suggested I open one here as well.

I'm running PD 0.47 on KXStudio (Linux) and am able to successfully get the abl_link~ external using deken (PD's package manager). However, when I try to instantiate an abl_link~ object, I get this error:

/path/to/mypdexternals/abl_link~/abl_link~.pd_linux: /path/to/mypdexternals/abl_link~/abl_link~.pd_linux: symbol _ZNKSt3_V214error_category10_M_messageB5cxx11Ei, version GLIBCXX_3.4.21 not defined in file libstdc++.so.6 with link time reference

A user over at libpd said "looks like the issue is due to differing versions of gcc. Your system is running an older version with a slightly older libc++. The answer seems to be to build with the following define: -D_GLIBCXX_USE_CXX11_ABI=0."

I think the solution to this is for the libpd/abl_link developer to recompile the external with that flag and upload it to deken, but I'm putting this here in case anybody else is having a similar issue.

Hi,

Your issue has nothing to do with link itself (so I would suggest to close the issue). It seems that your distribution or yourself did not properly build link.
I would suggest to do a clean checkout and build link from scratch. It should work fine then.

Alex.

I was having the same issue on Linux. Updating gcc to 4.9 or greater fixed this.
