如何转储conftest.c？

Question

我在使用交叉编译器链接到许多库时遇到问题.是否可以在每次生成文件时将文件conftest.c转储到安全位置？

我试图取消注释

rm -f conftest

从配置脚本,但它继续,就像它没有任何意义.

检查config.log,它包括失败的程序,例如:

...
configure: failed program was:
| /* confdefs.h */
| #define PACKAGE_NAME ""
| #define PACKAGE_TARNAME ""
| #define PACKAGE_VERSION ""
| #define PACKAGE_STRING ""
| #define PACKAGE_BUGREPORT ""
| #define PACKAGE_URL ""
| #define PACKAGE "libogg"
| #define VERSION "1.2.2"
| /* end confdefs.h.  */
| #ifdef __STDC__
| # include <limits.h>
| #else
| # include <assert.h>
| #endif
