Re: [Texmacs-dev] TeXmacs/S7

[Massimiliano Gubinelli]

Btw, the s7.c file is fully autonomous, so if you want just to try the interpreter without building all TeXmacs you can just do

gcc s7.c -o repl -DWITH_MAIN -I. -O2 -g -ldl -lm -Wl,-export-dynamic -Wno-stringop-overflow

See

Thanks for the tip with the --enable-guile2 flag. After installing some QT5 dependencies I was able to launch make. It failed with

I searched for a while but I was not able to pinpoint where what compiler flag is missing (or if it is anything else). I have libc6-dev installed.

I'm not sure s7 is correctly configured in all the platforms. Maybe you can try to add

#define MS_WINDOWS 1

to mus-config.h

for example.

Give a loot at  the comments at the beginning of s7.c. It could give some hints on how to properly configure it.

Dear all,
 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).

On Cygwin64 bit, there is a S7 boot issue :

Benchmark 1
832040
Time: 53
Booting TeXmacs kernel functionality

Thread 1 "texmacs" received signal SIGSEGV, Segmentation fault.
0x0000000100fb8f13 in s7_init () at ./Scheme/S7/s7.c:96752
96752   {


(gdb) l
96747   #if (!MS_WINDOWS)
96748   static pthread_mutex_t init_lock = PTHREAD_MUTEX_INITIALIZER;
96749   #endif
96750
96751   s7_scheme *s7_init(void)
96752   {
96753     int32_t i;
96754     s7_scheme *sc;
96755     static bool already_inited = false;
96756


I will need to look on this S7 code assumption for Cygwin

Compilation was fine :-(
