Hello Gnu exports. I ned help figuring out an issue with using a set of MinGW generated import libraries in a MSVC program (called 'hsmodem.exe'; "High-sped Modem"). I'm not using MinGW-w64, but TDM-gcc (gcc 10.3.0). Hopefully they are similar in this regard.
I've built these using MinGW (which hsmodem.exe depends on): 'liquid.dll.a' and 'liquid32.dll' (2747 exports) from the "digital signal processing" library at https://github.com/jgaeddert/liquid-dsp and: 'libcodec2.dll.a' and 'libcodec2.dll' (588 exports) a "low bitrate Digital Speech codec" library at https://github.com/drowe67/codec2 Both of the above .DLLs MUST be built with MinGW due to the heavy use of 'C99 complex' etc. So now, I'm trying to use the above imp-libs in a MSVC x86 'link.exe' step. The 'hsmodem.exe' program links fine, but running it fails with missing 'codec2_bits_per_frame' etc. Using 'pedump hsmodem.exe': ... Imports Table: liquid32.dll Import Lookup Table RVA: 000C73A4 TimeDateStamp: 00000000 ForwarderChain: 00000000 DLL Name RVA: 000C9188 Import Address Table RVA: 000AE3E4 Ordn Name 1 agc_crcf_create 2 agc_crcf_destroy 3 agc_crcf_execute 14 agc_crcf_reset 15 agc_crcf_set_bandwidth 58 codec2_bits_per_frame 60 codec2_create 61 codec2_decode 72 codec2_destroy 74 codec2_encode 104 codec2_samples_per_frame ... libcodec2.dll Import Lookup Table RVA: 000C73A4 TimeDateStamp: 00000000 ForwarderChain: 00000000 DLL Name RVA: 000C91B4 Import Address Table RVA: 000AE3E4 Ordn Name 1 agc_crcf_create 2 agc_crcf_destroy 3 agc_crcf_execute 14 agc_crcf_reset 15 agc_crcf_set_bandwidth 58 codec2_bits_per_frame 60 codec2_create 61 codec2_decode 72 codec2_destroy 74 codec2_encode 104 codec2_samples_per_frame ... ------------------- The same names and ordinals! And note, the 'Import Address Table RVA' is the same for both .DLLs. How could this happen? I suspect a bug in either ld.exe or MSVC's link.exe due to the large number of symbols. 'ld.exe' is: GNU ld (GNU Binutils) 2.36.1 'link.exe' is: 'Version 14.29.30138.0' Or could there be other issues to watch out for when using MinGW imp-libs with MSVC like this? -- --gv _______________________________________________ Mingw-w64-public mailing list Mingw-w64-public@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mingw-w64-public
