when make occurs errors

[chlizheng]

Hi.
I tried to build the tool to translate arm to llvm-ir. But when I run the sixth step "make llvm-mctoll" it cause errors as following:
"collect:2 errror: ld returned 1 exit status
make[2]: *** [bin/llvm-mctoll] error 1
make[1]: ***[tools/llvm-mctoll/CMakeFiles/llvm-mctoll.dir/all] error 2
make : ***[all] error 2
"
I don't know where is the problem. Could you give me some suggestions?
best regards

Thanks for your interest in the tool.

Can you please run the command 'make VERBOSE=1 llvm-mctoll' to get additional details of the failure and share them?

Please let me know of the OS and version on which you are attempting the build.

I expect the tool build and tests to pass on Ubuntu 16.xx, 17.xx and 18.xx.

Thanks!

Thanks, I run 'make VERBOSE=1 llvm-mctoll' but I didn't find more details and my Os is Ubantu-14.04.

And I want to translate arm assembly code to llvm-ir staticly for a try by translating simple code. In my opinion, I should translate arm instruction to llvm-ir one by one, and then replace arm instructions by a script. Maybe I think it too simple.

But I didn't find enough data to do this. It seems that the instructions about jump is difficult and the list of AMT is too large. What's more, I'm not sure how to translate some arm instructions to llvm-ir, and how to design whole infrastructure of target .ll file just according to assembly code?

Do you have some reference data about the translation job? And could you give me some references?
best regards.

As noted in README.md, at present development and testing is being done using Ubuntu 18.04. It is expected that build and test would work on Ubuntu 16.04, 17.04 and 17.10.

Support for codegen and/or ELF binary packaging differences on Ubuntu 14.04 needs to be added.

I am sorry that I do not yet have any references that describe this work yet. Will add them once we complete creating some.

Thanks!
