 |
|
I get the following error when attempting to compile a routine in 64-bit mode with a DLL created using MINGW64.
| Quote: | *** Error 902: Unable to read size of import symbols from F:\cmasterf95\RELEASE\WIN64\dxflib_dll_normal_64.dll.
|
Link to the 64-bit DLL is: https://www.dropbox.com/scl/fi/dz4lwx6vb1za7w4bq2sh0/dxflib_dll_normal_64.dll?rlkey=44jvtn6utv1zstk533c9p3n8w&dl=0
There may be a compile/library flag that is not being set properly when I compile and create the DLL. The batch file that does it is (in part):
| Quote: | g++.exe -c "Z:\CMASTERF95\dxflib_dll\src\dl_writer_ascii.cpp" -g -m64 -o build-Release\src_dl_writer_ascii_64.cpp.o -I. -I.
g++.exe -c "Z:\CMASTERF95\dxflib_dll\src\dl_dxf.cpp" -g -m64 -o build-Release\src_dl_dxf_64.cpp.o -I. -I.
g++.exe -c "Z:\CMASTERF95\dxflib_dll\src\dxf_interface_ftn95.cpp" -g -m64 -o build-Release\src_dxf_interface_ftn95_64.cpp.o -I. -I.
g++.exe -shared -fPIC -o build-Release\lib\dxflib_dll_normal_64.dll build-Release\src_dl_writer_ascii_64.cpp.o build-Release\src_dl_dxf_64.cpp.o build-Release\src_dxf_interface_ftn95_64.cpp.o -L.\lib -O2 -m64

Any insight into what I might do next would be helpful.
I had to resort to the MINGW64 C++ compiler because the code I'm using does things like
rather than
| Code: | | #include <limits.h> |
Without changing the code files for this kind of difference, SCC will not compile the files. Unless there is a flag I am unaware of. |

There does not appear to be a flag for SCC that allows for <limits>.
Have you considered using an IDE and "Replace in files" to replace <limits> by <limits.h>? Plato has this feature. |

| I was not using Plato, however this is an alternative that I'll try. |

| Update: The error message was due to the DLL import is not required for /64. |
