将 GhostPDL 编译为 DLL

Question

我正在尝试将 GhostPDL 从 Ghostscript 编译为 DLL，但我似乎无法正确执行此操作，因为它们确实有一个名为 plapi.h 的 API 文件，它指向该条目点:

GSDLLEXPORT int GSDLLAPI 
pl_main(int argc, char *argv[]);

如何让 NMake 将其编译为 DLL 而不是命令行“pcl6.exe”？我已阅读文档，但它没有提到编译为 DLL。

我可以使用 Visual Studio 中的 NMake 正常编译它，但这会创建“pcl6.exe”。

有什么建议吗？

我所要做的就是更改 make 文件中的代码

$(LINK) $(LCT) /OUT:$(TARGET_XE)$(XE) $(MAIN_OBJ) $(TOP_OBJ) @$(GENDIR)\ldall.tr @$(GENDIR)\lib32.rsp @$(LIBCTR)

至
