10. Change the standard AC_CHECK_LIB test for libbz2 in configure.ac to a |
| 61 |
|
custom one, because of the following reported problem in Windows: |
| 62 |
|
|
| 63 |
|
- libbz2 uses the Pascal calling convention (WINAPI) for the functions |
| 64 |
|
under Win32. |
| 65 |
|
- The standard autoconf AC_CHECK_LIB fails to include "bzlib.h", |
| 66 |
|
therefore missing the function definition. |
| 67 |
|
- The compiler thus generates a "C" signature for the test function. |
| 68 |
|
- The linker fails to find the "C" function. |
| 69 |
|
- PCRE fails to configure if asked to do so against libbz2. |
