Question

我将名为CplusplusObjects的文件夹中的所有cpp文件编译成libmps-cplusplus.a。当我尝试使用libmps-cplusplus.a在另一个makefile中创建共享对象时，我得到libmps-cplusplus.a：无法读取符号：文件格式错误**错误。

在搜索类似的问题时，我发现这个问题与32位和64位版本的混合有关，但我在这两个make文件中都特别提到了64位。

Objdump -af libmps-Cplusplus.a如@EtanReisner所建议的libmps-Cplusplus.a表示，有一个名为OsrpGroomingCapacityPlanning.o的文件被编译为文件格式elf32-i386。这导致＆＃34;无法读取符号：文件格式错误**错误＆＃34;。为了解决这个问题，我必须从存档中删除OsrpGroomingCapacityPlanning.o并手动编译它并将其与其他.o文件一起再次存档。
