OK, I learned something from your bug :-) However, given that the issue does not occur on my system (ubuntu 16.04), I'm afraid I can't help sorting it out. Let us know if you come to understand the origin of the problem in your setup.

When a variable assignment is before the command (not on a separate line) sh or bash automatically export the variable for this command (not for the following lines of sh input).

Example:

COLOR=full ls

In this example the shell variable COLOR is exported while running the command ls.

So the error is in something other.

Oh, I see. It wasn't clear that was input. Anyway, I still think I have a point since the instructions are to :

export PATH=...

The following is NOT what it prints, but it is what I type in the Bash command line:

PATH=$PATH:/usr/local/stow/TeXmacs-1.99.6-10945-i386-pc-linux-gnu/bin TEXMACS_PATH=/usr/local/bin/TeXmacs-1.99.6-10945-i386-pc-linux-gnu strace texmacs.bin

Yes I saw, and this is precisely why I suspect something is wrong with the PATH: I find it strange that it prints PATH=$PATH:... where $PATH has not been expanded.

Philippe, you see that I do have PATH setting in my bug report.

It looks like a misconfiguration of the PATH so that the wrapper script does not find the executable. Maybe there was an error while manually setting up the PATH? This installation procedure is not very user-friendly...

If you cannot find how to correct for this you can install a deb for debian 9 from this location:

https://software.opensuse.org/download.html?project=home:slowphil:texmacs-devel&package=texmacs

I've had reports it works.

I have installed http://www.texmacs.org/Download/ftp/tmftp/generic/TeXmacs-1.99.6-B.tar.gz into /usr/local/stow/TeXmacs-1.99.6-10945-i386-pc-linux-gnu

Then I try to run TeXmacs (under strace to make the error more clear):

PATH=$PATH:/usr/local/stow/TeXmacs-1.99.6-10945-i386-pc-linux-gnu/bin TEXMACS_PATH=/usr/local/bin/TeXmacs-1.99.6-10945-i386-pc-linux-gnu strace texmacs.bin
execve("/usr/local/stow/TeXmacs-1.99.6-10945-i386-pc-linux-gnu/bin/texmacs.bin", ["texmacs.bin"], 0x7ffe7e4bc630 /* 43 vars */) = -1 ENOENT (No such file or directory)
fstat(2, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 0), ...}) = 0
write(2, "strace: exec: No such file or di"..., 40strace: exec: No such file or directory
) = 40
getpid()                                = 7105
exit_group(1)                           = ?
+++ exited with 1 +++

No idea why the above nonsense happen. Please make TeXmacs work again.

It happens on Debian 9.
