Re: hypot with gsl static library

You can define hypot to _hypot at the start of your program (in C: #define
hypot _hypot) and then recompile.

In Visual C++ the POSIX names, such as hypot, are automatically converted to
the MSVCRT names with underscore prepended, unless some specific option has
been defined to turn off this conversion. I would guess that with Visual
Basic there is a similar option; apparently it has been turned on when the
program was compiled.

Subject: [GnuWin32-Users] hypot with gsl static library


Hi,

Any sugestions for a newbie will be greatly appreciated!

I am trying to statically link libgsl.a with a program made in Basic.
I get the following error:
gsl.lib(matrix_oper.o) : error LNK2001: unresolved external symbol '_hypot'

My link (MS-2.50.4048) command is:
link /entry:WinMain /NODEFAULTLIB /SUBSYSTEM:CONSOLE /INCREMENTAL:NO 
/RELEASE /NOLOGO /OPT:REF /ALIGN:4096 -out:MI.exe MI.obj MI.rbj xst_s.lib 
xsx_s.lib xio_s.lib xma_s.lib msvcrt.lib gsl.lib gslcblas.lib xblib.lib 
kernel32.lib advapi32.lib user32.lib gdi32.lib comdlg32.lib winspool.lib

Note, please, that I am linking against msvcrt.lib, which has got a hypot 
symbol defined (in fact is _hypot) and my compiler does not accept /D 
option.

Yes, I read the docs, but before I will attempt to compile the lib again and 
replace hypot with gsl_hypot, is there any other solution to this? Other 
library available? Any linker option? Anything?

Thanks,

Liviu
