Oneiric 中的 GSL 库有问题吗？我在链接时遇到了麻烦，但不明白为什么——它在 10.4、10.10 和 11.4 中运行良好。
编辑：首先进行小测试用例，完整问题如下：
在 Natty 上运行良好：
$ 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
$
Oneiric 失败：
$ 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
但这在 Oneiric 上有效：
$ g++ gsl-test.cpp -lgsl -lgslcblas
$ ./a.out
我怀疑 g++ 的工作方式存在一些差异（4.6.1 与 4.5.2）。
编辑：
$ 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
这是完整的问题，它似乎与我上面的测试用例有点不同，因为它仍然没有通过在行-lgsl -lgslcblas末添加以下内容来修复：

如果我这样做，无论是在 Natty 还是 Oneiric 上，我都会得到同样多的未定义的引用：
$ g++ gsl-test.cpp -lgsl
目前还不确定该如何理解。
答案1
尝试-lgsl先写-lgslcblas。我知道这很蠢，但对我来说这很有效...
答案2
问题是libtemt.so.5.2.3也链接到了 GSL 库，而且顺序错误。不知何故，那个链接成功了，但导致下一个链接失败。一旦我使用libtemtordering:进行链接-lgsl -lgslcblas，我就可以css以相同的正确顺序链接可执行文件，并且成功了。现在我只需要弄清楚如何说服 CMake 编写正确的link.txt文件。
