I think you can put-Wl,-export-dynamic -lm -ldlin LD_FLAGS or somewhere where there are already some -l flags, like in the GUILE_LDFLAGS, etc.. I do not remember exacly the name.MaxOn 18.

I looked in src/src/makefile but got lost finding where to add/remove compilation flags.Best,Álvaro.On Mon, 18 Jan 2021 at 15:42, Massimiliano Gubinelli <m.gubinelli@gmail.com> wrote:I'm not sure, but on the webpage of s7 the standard compiling flags aregcc -c s7.c -O2 -I. -Wl,-export-dynamic -lm -ldlyou might try to add -Wl,-export-dynamic .

Maybe you can try to add#define MS_WINDOWS 1to mus-config.hfor example.Give a loot at the comments at the beginning of s7.c. It could give some hints on how to properly configure it.maxOn 17.

an *unofficial* port of TeXmacs to S7 is essentially complete. I do not have any particular bug on my list. If you feel adventurous you can try it and report problems, this will help me to finalize it, you find it here:
https://github.com/mgubi/texmacs/tree/s7
It is still a development version, use it to your own risk and do not advertise it to regular users.
The plans is to wait for 2.1 and then evaluate what we are going to do wrt. Scheme support. In the meantime these ports allow me to learn better how the scheme code in TeXmacs works and hopefully to provide a stable base for the next 20 years of TeXmacs :) (be it with Guile, S7 or whatever else we decide to use).
