Would it be possible to have a newer version in next release of DSL ? I tried a simple hello world, and the stdio.h library is missing

Thanks a million in advance

Hi there 
DSL does not habe those .h - files
You dont need them anyway.
There is a tcclib.h which includes a lot of them.
You can just copy those you need into it.
Right now I'm writing a little tutorial for TCC and DSL.
try the following:
| Code Sample |
| #include "/usr/lib/tcc/include/tcclib.h" |
and compile it with
| Code Sample |
| tcc -o yourfile -lstdc++-3-libc6.1-2-2.10.0 yourfile.c |
That should work.
The .h - files "only" contain the declaration. You can declare them yourself if you like...
Linking them to the correct libs is the important thing!
You can make your own .h-header-file or add needed functions to that tcclib.h
Hope this helped...
Ask again if not... I think TCC is wonderful
and if you are interessted watch out for that little example-proggy I'm gonna post soon
Off now,
enthusi

This is good information. I'm looking forward to your tutorial.Since you seem to know something about tcc, do you know what the problem is when compiling a simple "hello world" program results in:
tcc: _start not defined
Thanks,

Hi It will be ready soon
Your error sounds familiar but I dont remember
Maybe you can post or email your c-programm and the command line you use for compiling?
I could test it here then...
Greet's,
Enthusi

Hi there I just uploaded a small C/TCC - Tutorial for DSL.
I wrote a small program during christmas when I had nothing with me but my beloved DSL-cd
I commented almost every line of the code...
I was quite sceptical about TCC and wanted the good "old" GCC...
TCC may not suit for general source-compilation but it is astonishing powerful for own little projects.
Maybe someone's interessted - please feel free to comment on it. I will start a thread in HOW-TOs. And hopefully you can help me with
comments on how to improve it.
I think it would be nice to add stuff like this (ok, to be honest: please add THIS one :-) to DSL... It takes up almost no space and can add many many fun hours for the DSL-user...
Get it here:
< http://allthegoodthings.tripod.com/damnsmalllinux >
or type:
| Code Sample |
wget http://allthegoodthings.tripod.com/damnsmalllinux/tcc_tuturial_v0.1.zip |
and unzip it...
Good night now,
Enthusi

Actually I experienced this problem with tcc 0.9.20 on FeatherLinux (which is very similar to DSL). The code is simply:
| Code Sample |
#include <tcclib.h> void main( void ) { printf( "hello, world\n" ); } |
and compiled with:
| Code Sample |
tcc -o hello -lstdc++-3-libc6.1.2-2-2.10.0 hello.c |
results in "tcc: _start not defined"
(I may not have the library filename correct but you get the idea.) Also compiling with "-c" creates hello.o but the same error occurs when attempting to link and create the executable.
As mentioned this program runs with the tcc "-run" option.
Any ideas are welcome...
Thanks,

@enthusi: Am I wrong or is the command line parameter argv[2] never taken into account? I was using Vs 0.1 of your tiny tcc tutorial and I really like it. Well done!tbeu

@theudamnit! you're right
Seems like an version 0.1.1 will be up sooner than I thought.
I inserted the argv[]-options afterwards and obviously forgot one.
argv[2] is menat for ib in line 87.
Just change ib=-1.25 to ib=atof(argv[2]).
Thanks for your comment on this!
@catfish
I will check on this today!
First ideas would be:
- does #include <tcclib.h> work, or does is have to be
#include "/usr/lib/tcc/include/tcclib.h" ?
- a void-main-function is not very common and not necessaryly supported.. Maybe it is only allowed with C++.
But as I said - I will check this out today and hope to be more helpful then
@all
have a nice day,
enthusi

Hi again.@catfish
I just tried and it works fine over here...
sorry
I found a little error though: you mistyped the lib.
-lstdc++-3-libc6.1.2-2-2.10.0
instead of
-lstdc++-3-libc6.1-2-2.10.0
I tried to compile with the latest TCC 0.9.20.
I think it would be best to include the tcclib.h with path.
I dont know FeatherLinux but there SHOULD be no problem...
In general it can be said that
when it runs with "-run" but creates no valdid executable it is not linked correctly to some libs...
I hope this helps even though I told nothing new.
Check for the lib-name and path
good luck,
enthusi

Hi folks.There was one little line to change - so here comes the new version.
Nothing bad but I want to keep up to date.
So better forget the direkt link and just see whats up on this site :
< TCC - Tutorial 16.01.04 v0.1.1 >
Have fun with it and please post wishes of any kidn to me

Now, is this just a c compiler, or can it do c++ as well ? I'm working with c++, and need a compiler for that, but don't like to have to wait 10 mins for my redhat to boot on my old 233 laptop.

AFAIK, tcc only supports C. Perhaps you'd be interested in uClibc, which has a small C++ compiler as well.

Thing is, I don't wanna make my own Knoppix or do an HD-install (not yet anyway). Besides, gotta find a place that'll teach me how to.
