December 29, 2017 What could this OptLink Error mean? | ||||
---|---|---|---|---|
| ||||
I was building one example of DLangUi (dub build --build-mode=allAtOnce --build=debuglinker) and it did compile but the linker started to complain. I did notice it seemed to be related to the standard library, so I updated it and DRuntime to the lastest master, rebuilt them and replaced phobos.lib with the result. I also removed the binary and .dub directory from DLangUI to force Dub to rebuild it, which it did. Still the linker complains, but about a different symbol: ..\..\lib\dlangui.lib(colors) Error 42: Symbol Undefined __d_switch_string Does anybody have an idea what could be causing this? |

The deps have to be rebuild too. Assuming paths and everything is okay (should be the case when you build ~master as indicated in the wiki) just add --force.

After downloading dmd 78, it started to work. It's likely you were right about the issue, DUB rebuilt everything after detecting new compiler version.
Sorry for my late reply.

From a compiler version to another, the ABI can change (examples are: mangling, new overloads as seen with format a couple of months ago). You compiled the program with a slightly different ABI than the one used to compile the deps as static libraries.
I don't know why DUB didn't detect this but as said user1234 always try " --force" on DUB or rebuild deps manually to eliminate this possible cause of problems.
