Q: lapackpp v2.2.0 lib usuage

Dear Everyone,

I was trying to use Lapack++ v2.2.0 on my Linux (slackware 10) , the command
is like this:

gcc -o test Mat.o
test.o -L/local/d0p1/hw/lapackpp-2.2.0/lib -L/local/d0p1/hw/LAPACK -llapackp
p -llapack_LINUX -lblas_LINUX -lm

but got the following error message:

/local/d0p1/hw/LAPACK/liblapack_LINUX.a(ilaenv.o)(.text+0x4c): In function
`ilaenv_': undefined reference to `s_copy'
/local/d0p1/hw/LAPACK/liblapack_LINUX.a(ilaenv.o)(.text+0xe2): In function
`ilaenv_': undefined reference to `s_copy'
....
/local/d0p1/hw/LAPACK/liblapack_LINUX.a(dormbr.o)(.text+0xb5): In function
`dormbr_': undefined reference to `s_cat'
....
/local/d0p1/hw/LAPACK/liblapack_LINUX.a(dormlq.o)(.text+0x569): In function
`dormlq_': undefined reference to `s_cat'
....
....
/local/d0p1/hw/lapackpp-2.2.0/lib/liblapackpp.so: undefined reference to
`d_sign'
collect2: ld returned 1 exit status
make: *** [test] Error 1.

Does anyone have any idea why this happened? The blas and lapack library
files are under directory /local/d0p1/hw/LAPACK, named libblas_LINUX.a and
liblapack_LINUX.a, respectively. Lapackpp 2.2.0 is installed under
/local/d0p1/hw/lapackpp-2.2.0, and so the lib files are under
/local/d0p1/hw/lapackpp-2.2.0/lib. The fortran compiler used for compiling
the packages was g77. The 'make check' reports 'all passed'.

The code actually only has a variable declaration in it (of cause other
lines, and had my own matrix class in it, but they were running correctly
before and didn't use any of the lapack stuff):
#include "gmd.h"

....
LaMatGenDouble myMatrix(3,4);
....

And the error messages were the same even without this declaration.

Any advice is appreciated. Thank you very much,

Hongfang

Try giving the linker the following flag

-lg2c

Just a guess, but the Lapack++ home page gives a linking example as:

gcc -L/usr/local/lib -llapackpp -lblas -llapack foo.o

Note that -lblas comes /before/ -llapack. Maybe try changeing the link
order (and perhaps libm is not required...)

Thank you for you reply. Used the flag, and got the following error message:

../test error while loading shared libraries: liblapackpp.so.1: cannot open
shared object file: no such file or directory.

Could you please give me some hint of this?

Thanks a lot,

Hongfang

re: Q: lapackpp v2.2.0 lib usuage

Solved!

first, add -lg2c when linking
second, set environment variable:
export
LD_LIBRARY_PATH=/local/d0p1/hw/lapackpp-2.2.0/lib:/local/d0p1/hw/LAPACK

cheers.

Dear,
No have lib folder in lapackpp-2.2.0 folder.
Please check it again.
Anyway, I have installed lappackpp successful in my debian linux. After I compiled my lapackpp c++ file, I executed the out file. The system told that
