I am using MinGW (actually MXE for cross compilation on Linux), but there seems to be a problem with including libcurl as a static library via -DCURL_STATICLIB. With explicitely exporting the symbols for Windows, the problem is solved, and the dll are loaded correctly. Thanks, Thomas -- "Ich komme aus dem Staunen nicht heraus."

[PD-dev] Question about error in external
Hello, while I am working on PuREST JSON, I have gotten an interesting error, but only on Windows: Two of my objects do not load correctly with the message: load_object: Symbol "rest_setup" not found On Linux, this works without any problems, as do the other objects in Windows. What is different with [rest] and [oauth] objects? Both are using a lot of libraries, including libcurl, and so the resulting dll files are quite large (3.5 and 4.5 MB). Can this be the reason for that error? Thanks for your help, Thomas -- "Anything can be a tool - poverty, war. War is useful because it is effective in so many areas."
