Problemas com a vinculação da GSL / CBLAS

Question

EDITAR : problema resolvido, veja minha resposta abaixo.

Existe algum problema com a biblioteca GSL no Oneiric? Estou tendo problemas para vincular e não entendo o porquê - isso funciona bem em 10.4, 10.10 e 11.4.

EDITAR : casos de teste pequenos primeiro, o problema completo está abaixo:

Funciona bem em Natty:

$ cat /etc/issue
Ubuntu 11.04 \n \l

$ cat gsl-test.cpp
#include <gsl/gsl_errno.h>
void handler(const char *, const char *, int, int) { }
int main() { gsl_set_error_handler(handler); }

$ g++ gsl-test.cpp  ## Expect problems since libraries not linked in
/tmp/ccnjUNdv.o: In function 'main':
gsl-test.cpp:(.text+0x16): undefined reference to 'gsl_set_error_handler'
collect2: ld returned 1 exit status

$ g++ -lgsl -lgslcblas gsl-test.cpp
$ ./a.out
$

Falha no Oneiric:

$ cat /etc/issue
Ubuntu 11.10 \n \l

$ cat gsl-test.cpp
#include <gsl/gsl_errno.h>
void handler(const char *, const char *, int, int) { }
int main() { gsl_set_error_handler(handler); }

$ g++ gsl-test.cpp
/tmp/ccWKJMov.o: In function 'main':
gsl-test.cpp:(.text+0x16): undefined reference to 'gsl_set_error_handler'
collect2: ld returned 1 exit status

$ g++ -lgsl -lgslcblas -lm gsl-test.cpp
/tmp/ccV0UIx5.o: In function 'main':
gsl-test.cpp:(.text+0x16): undefined reference to 'gsl_set_error_handler'
collect2: ld returned 1 exit status

Mas isso funciona no Oneiric:

$ g++ gsl-test.cpp -lgsl -lgslcblas
$ ./a.out

Eu suspeito que há alguma diferença em como o g ++ está funcionando (4.6.1 vs. 4.5.2).

EDITAR :

$ nm /usr/lib/libgslcblas.so
nm: /usr/lib/libgslcblas.so: no symbols
$ nm /usr/lib/libgslcblas.a|grep 'cblas_zher2k\|cblas_dtrsm\|cblas_zhemm'
00000000 T cblas_dtrsm
00000000 T cblas_zhemm
00000000 T cblas_zher2k

E aqui está o problema completo, que parece ter um sabor um pouco diferente do meu caso de teste acima, pois ainda não foi corrigido colocando -lgsl -lgslcblas no final da linha:

Eu recebo a mesma quantidade de referências indefinidas se eu fizer isso, seja em Natty ou Oneiric:

$ g++ gsl-test.cpp -lgsl

Não sei o que fazer com isso ainda.

    

Answer 1

O problema era que libtemt.so.5.2.3 também estava vinculado às bibliotecas da GSL e na ordem errada. De alguma forma, esse link teve sucesso, mas causou a falha do próximo. Uma vez que eu vinculei libtemt com a ordenação: -lgsl -lgslcblas , então eu poderia vincular o executável css com a mesma ordenação correta e foi bem-sucedido. Agora eu só preciso descobrir como convencer o CMake a escrever o arquivo link.txt correto.

    

Answer 2

Tente escrever -lgsl antes de -lgslcblas . Eu sei que é estúpido, mas para mim funciona ...
