I had never heard of GnuRoot before this thread, and I was already annoyed at the non-standard paths in Termux, so I decided to look at GnuRoot.

I downloaded GnuRoot at lunch yesterday, then discovered I needed GnuRoot Wheezy as well, then when I ran that it told me those two options were obsolete and I needed GnuRoot Debian, so I uninstalled the other two and downloaded that. Looked fine. I then did 'apt-get update' and got an error message. It turns out that my employer blocks the Debian sites, for some reason.

So yesterday evening I did 'apt-get update' and 'apt-get upgrade'; that took a while. Then I tried to wget the Gambit tgz file, but discovered neither wget nor curl is automatic with GnuRoot Debian, so I fetched both.

Then I downloaded Gambit, untarred, and did './configure'. But configure wasn't executable, so it didn't work. I said 'chmod 777 configure' but the execute bit still wasn't set. Searching Google I discovered that error occurs because the sd card is mounted noexec, but I don't have an sdcard, so I'm baffled.

Anyway, I did 'sh configure' and got an error message that gcc isn't installed. What kind of Debian is this? So I fetched gcc and did 'sh configure' again. I got another error message, I forget what.

So I gave up and went to bed.

I'll keep dealing with this over the next few days, and let you know when I make some progress.

Thanks to everyone who offered advice.

Dear Phil,

so I dug out my Nexus 9 tablet and tried to recompile gambit 4.8.5.

The procedure is a little more involved than I had remembered. I used the following commands
to compile gambit:

termux-fix-shebang configure gsc-boot.unix install-sh relpath mkidirs
TMPDIR=$HOME/tmp CONFIG_SHELL=$PREFIX/bin/sh CC=clang LIBS=-llog ./configure --prefix=$HOME/gambit-tmp
make
make install

Comments:

1.) You must update the shebang path in 5 files, not 2 as I had
    previously written. You can use the termux-fix-shebang utility to do this
    (as shown above).
2.) TMPDIR=$HOME/tmp is necessary as /tmp is not writeable for Termux apps.
3.) Recently Termux has switched to clang instead of gcc. Unfortunately on my
    tablet clang runs out of memory compiling gambit. I did not have this problem
    with gcc.

Nevertheless I hope this helps. Maybe clang is a little less memory hungry on your 32bit
(ARM7) machine. If all fails, the GNUroot option may prove better for you. There you
can simply "./configure; make; make install".

I wish you good luck. Do not hesitate to contact me, if I can be of further help.

Best regards,

Alexander
