Hi @tulsidas, I also encountered this issue on FreeBSD, when using recent versions of GCC. It seems to be caused by:

• flex that generates C code from lexer files, where the order of includes has string.h being included before stdlib.h
• gnulib that creates replacement header files, that implies this ordering
• probably some other compiler-related cause that I haven't identified yet.

I could make it work by using clang as the compiler on my platform. Can you give it a try?

# I haven't checked, I would expect the package name to be clang, please verify how it's labelled
sudo apt-get install clang

./bootstrap.sh
./configure CC=clang
make

@keldonin that worked! thanks for the quick response 👍🏼

[keldonin]

@tulsidas you welcome. There is nevertheless an underlying issue that we must address.

[tulsidas]

feel free to contact me if you need to try out something on Linux

[keldonin]

Out of curiosity, what is the linux distribution you run? Is it just plain Debian?

[tulsidas]

Yes, Debian testing thou

$ cat /etc/os-release

Hi @tulsidas, thanks for the information. I see this version will be released by June 10th. I'll give it a try - on a side note, the project compiles like a charm on the current Debian release (11).

@keldonin FYI I just tried building today (a fresh clone) and it worked ok

As of release 2.6.0 I intend to ship binaries. There are already RPMs available, Debian packages to come later. You could try to deploy the RPM using alien on Ubuntu.
