undefined symbol: BZ2_bzDecompress

Do you have libbz2 installed? "bzip2 -V" depends on another package it
seems.
This is from debian repos:
libbz2-1.0 -
high-quality block-sorting file compressor library - runtime
bzip2 -
high-quality block-sorting file compressor - utilities

Bruno

Yes, It is installed and available at /usr/lib64/libbz2.so and linked as below
ldd /usr/lib64/libbz2.so
 linux-vdso.so.1 => (0x00007fff959ff000)
 libc.so.6 => /lib64/libc.so.6 (0x000000309ca00000)
 /lib64/ld-linux-x86-64.so.2 (0x000000309c200000)

Is libbz2.so a dependency of yade's libcore.so on your system?

ldd lib/libcore.so
  ...
  libbz2.so.1.0 => /lib/x86_64-linux-gnu/libbz2.so.1.0 (0x00007f2ce1703000)

We do actually use BZip2, but on Debian systems it is, probably
linked to some other libraries, which we use. So we do not need
to do it explicitly. It seems, on RedHat-systems, it is not always so.

I have committed the fix [1]. Please, check it out and let us know,
whether it works for you.

I have compiled your latest github commit and now the following error has appeared,

Welcome to Yade Unknown
Traceback (most recent call last):

Carl

Very strange, is it an old Redhat-system?

Please, update your code and test again.

Thanks Anton Gladky, that solved my question.

I am trying to build yade-0.90.3 in the same system and faced the same bug before. Any suggestions for older version? Thanks for your previous commits.

We do not have resources to support older versions. If you do really need that,
you can backport the following commits [1] and [2]:

[1] https://github.com/yade/trunk/commit/2b0ed69878e46b8f1972058285389c74424e6ecf
