ar.exe: obj\Debug\main.o: No such file or directory

Trying to build a static library from the jsoncpp library (amalgamated version) so I can link it with my main project that uses it (but errors due to multiple "undefined references" from the library). However, it errored to (including full log):

When I was creating the project via the wizard, I changed no options other than name of the project. Is there something I missed or is there something wrong?

Does D:\_a\jsoncpp\main.c exist? Can you remove the underscore from the path and try again?

[creativegamer_03]

Well, that's the actual folder's name ("_a") since I want it above other folders when I access D:\. Anyways, should it be a .c file and not a .cpp file? The JsonCPP library is in .cpp source file format, with some header files in a separate folder in it.

File hierarchy of jsoncpp (amalgamated):

So it's not D:\_a\jsoncpp\main.c but D:\_a\jsoncpp.cpp

[creativegamer_03]

Oops. Sorry to confuse you about the path. The full path is actually D:\_a\jsoncpp\jsoncpp.cpp.
What I meant there is the projects folder being named "_a". I forgot to mention that "jsoncpp" is under that folder, of which this folder was created by Code::Blocks from the wizard.

You must remove main.c from the project and add jsoncpp.cpp. Probably main.c is the default file created by the wizard, and it is not necessary.

I just did. I did replace it, as well as copying in also the jsoncpp folder containing its header files.

[Miguel Gimenez]

Does it work now?

[creativegamer_03]

nope. same thing.

[Miguel Gimenez]

The log must be different, please post it.

[creativegamer_03]

The log was the same as the first post. However I just solved my problem.

So, I was quite curious what the .cbp file looks like inside, which I then found out to be in an XML format. Looking through the tags, I found the tag '<Unit filename="main.c">'. I tinkered it by replacing it with "jsoncpp.cpp".
At first, I thought it didn't do anything when I try to rebuild it.
Then I thought of relaunching Code::Blocks and open the project file afterwards to load up from the modded .cbp file.
And so I did, then opened the "jsoncpp.cpp" file, pressed F9, and it is fixed.
