[WIP] Yabasic 2.9.9 (structures and plugins merged)

[psnake]

This release is the merge of my work on plugins (2.9.7) and Thomas work on structures (2.9.. There's nothing actually new.

Also, regarding the build system, Windows users that want to compile yabasic now have the project files for codeblocks. I'll write a blog post regarding those later this week.

Source: http://basicprogramming.org/main/files/yabasic-src-beta-2.9.9.zip
Windows Binary: http://basicprogramming.org/main/files/yabasic-bin-beta-2.9.9-windows.zip

EDIT: it's a WIP because Thomas has not yet reviewed the code.

EDIT2: like cybermonkey noticed, the Makefiles only work on Windows. I'll try to fix this as soon as possible.

Best Regards,
PSnake

Off-topic: I finally have a new PC and with it Windows 7 and it will be my main platform for development. I just wanted to give a big thanks for all that helped me before I had Windows.

Hi psnake ...
So i need CodeBlocks editor with MingW ?
And then i can compile YaBasic src to final exe?

[Cybermonkey]

Ok, looks fine, but the makefile is now Windows-only 
(Had to adjust several lines in the makefile to compile under Linux)

@aurelB
I tested it with Codeblocks+MinGW, but since CB supports other compilers, it may also work with others.

@cybermonkey
I only tested on windows, but I think it's only a matter of changing

Code:

SYSTEM = SYSTEM_WINDOWS

to

Code:

SYSTEM = SYSTEM_UNIX

in src/Makefile and src/plugins/Makefile

Nope that's not all because it refers to an "external" library

Code:

YABASIC_LIBS = -Lexternal/lib/ -lm -ldl

which results in compile errors:

Code:

gcc  -o ../bin/yabasic function.o io.o main.o parse.o plugin.o scan.o symbol.o -Lexternal/lib/ -lm -ldl -std=c99 -Wall -Wextra -pedantic -g -DSYSTEM_WINDOWS                                                                                                           
plugin.o: In function `ybp_load_plugin':

/home/markus/Downloads/yabasic/src/plugin.c:39: undefined reference to `dlerror'
/home/markus/Downloads/yabasic/src/plugin.c:47: undefined reference to `dlsym'
/home/markus/Downloads/yabasic/src/plugin.c:49: undefined reference to `dlerror'
/home/markus/Downloads/yabasic/src/plugin.c:54: undefined reference to `dlsym'
/home/markus/Downloads/yabasic/src/plugin.c:56: undefined reference to `dlerror'
plugin.o: In function `ybp_load_cfunction':
/home/markus/Downloads/yabasic/src/plugin.c:98: undefined reference to `dlsym'
collect2: ld returned 1 exit status

Instead I have to do this in the Makefile:

Code:

YABASIC_LIBS = -lm -ldl

Ok, that's an easy task but imagine someone don't know? I first startled and though, uh oh it doesn't build anymore on Linux until I remembered that Windows needs the "external" shipped libs.

Sorry, this only compiles yabasic but NOT the plugin! This happens when trying to compile the plugin

Code:

markus@desktop:~/Downloads/yabasic_neu/src/plugins$ make build
gcc -std=c99 -shared -O2 -Wall -Wextra -pedantic -g -DSYSTEM_UNIX -I. testdrive/testdrive.c ybp_interface.c -o testdrive.ybp
/usr/bin/ld: /tmp/ccWr92ak.o: relocation R_X86_64_32 against `.rodata.str1.8' can not be used when making a shared object; recompile with -fPIC
/tmp/ccWr92ak.o: could not read symbols: Bad value
collect2: ld returned 1 exit status

Seems I will have to recompile ybasic with -fPIC (64bit issue?)

Okay, this is what I've done: I added -fPIC in the makefiles in src/plugins AND src
Result:

Code:

gcc -std=c99 -shared -O2 -Wall -Wextra -pedantic -g -fPIC -DSYSTEM_UNIX -I. testdrive/testdrive.c ybp_interface.c -o testdrive.ybp
mv *.ybp ../../bin/plugins/

[psnake]

Ok, thanks, I'll mark this one as Windows-only for now, until I rewrite the Makefiles.

Sorry for making things more complicated than they are. Of course a plugin is not meant to be a stand-alone programm.  Unfortunately an example is missing in this WIP ... Tried the one of 297 ... but it didn't work.

[psnake]

The example was moved to the tests directory (tests/plugin.yab). if it doesn't print anything then it works fine.

PSnake

[aurelB]

No problem i have Codeblocks+minGW
I will try...

[psnake]

I uploaded a new package. The only changes are: src/Makefile and src/plugins/Makefile
If you are on Linux (or other *NIX) you have to comment SYSTEM_WINDOWS and uncomment SYSTEM_UNIX.

About the 64bit issue I'm currently not able to check this. Everything is fine on 32bit Linux and Windows (at least on my machine )

PSnake

[Cybermonkey]

The example was moved to the tests directory (tests/plugin.yab). if it doesn't print anything then it works fine.

PSnake

Don't know for sure (I am at my shop now), but it says something like "unknown command 9" or so ...

[psnake]

Oops, must have uploaded an older version of the code when changed Makefiles.
The problem was in a internal command not being implemented when I merged both 2.9.7 and 2.9.8.

I'll upload it again.

EDIT:
link: http://basicprogramming.org/main/files/yabasic-snapshot-2.9.9.zip
This package is a little bigger because it's a direct snapshot of my work right now and so it includes some unnecessary clutter.

PSnake

[Cybermonkey]

Okay, now it works fine. But, please, please add the -fPIC to the Makefile under src/plugins. This also works with 32bit operating systems and makes IMHO no difference but this is the only way to compile on 64bit Linux.
BTW, does the SDL plugin work under Windows?

[psnake]

Yes, although it's not finished yet.

About the -fPIC I'll add it as soon I get the chance. That flag is only needed on the plugins or the yabasic Makefile needs it too?

PSnake

[Cybermonkey]

The flag is only needed on the plugins.
But I tried now the graphics lib on Windows Vista (yabasic main.yab, correct?) and it failed. Something like "Yabasic doesn't work properly" and "Close the program", "Search for solution online" etc. (Don't know the proper English names since I have a German Windows). And SDL.dll is installed, btw.
