Re: [Ngspice-devel] bug fixes

[Holger V. <hol...@un...>]

Dear all,

before releasing ngspice 18, we should put a little bit more work into 
some issues:

My personal feeling is that the tclspice integration using libtool is 
not yet ready.
I cannot make tclspice fronm CVS sources under MINGW.
I cannot make tclspice from CVS sources under LINUX (SUSE 10.2).
The error messages are the same in both cases and are totally cryptic 
(thanks to libtool):

libtool: link: can not build a shared library
libtool: link: See the libtool documentation for more information.
libtool: link: Fatal configuration error.

CVS code has to be the norm, not a personal setup of ngspice/tclspice! 
So if there is anybody out there who can make tclspice on either OS from 
fresh code (really fresh, that is starting with an empty directory, 
copying the top level CVS file only and then calling CVS to download 
everything), please let me know. I would be happy to understand what is 
going on.

Compilation of ngspice with libtool is a nuisance, because every *.o 
file is created twice.
I have reported on these matters some time ago, and we should resolve 
these problems. However, if we want (need?) to stick to libtool, 
somebody should take care and make himself a specialist. We cannot 
introduce this tool and have only a coarse understanding of what it is 
doing!

Some additional remarks:

What will be the new welcome message (current one below)?

During cimpiling there are some warnings (similar under MINGW and LINUX).
A summary is below, skipping minor ones:

MINGW:
cmath2.c: In function `cx_rnd':
cmath2.c:217: warning: implicit declaration of function `random'
mifsetup.c: In function `MIFunsetup':
mifsetup.c:524: warning: case value `-1' not in enumerated type 
`Mif_Cntl_Src_Type_t'
mod_yacc.c: In function `mod_yyparse':
mod_yacc.c:1455: warning: implicit declaration of function `mod_yylex'
mod_yacc.y:493: warning: too many arguments for format
main.c: In function `xmain':
main.c:740: warning: implicit declaration of function `srandom'

in LINUX
equality.c: In function ‘AlmostEqualUlps’:
equality.c:56: warning: implicit declaration of function ‘llabs’
equality.c:56: warning: incompatible implicit declaration of built-in 
function ‘llabs’

We should remove the sources of the warning by improving the code. I 
will take care of llabs and (s)random.
