OSQP installation error

[shashins]

I am getting following error message while trying to run using OSQP in Julia 1.1

[ Info: Precompiling OSQP [ab2f91bb-94b4-55e3-9ba0-7f65df51de79]

Could you post the content of the file given by joinpath(dirname(dirname(pathof(OSQP))), "deps", "build.log")

[shashins]

bash: syntax error near unexpected token `dirname'

[blegat]

You need to enter it in the Julia REPL

[shashins]

Following error message I am getting:

ERROR: UndefVarError: OSQP not defined
Stacktrace:

[blegat]

You need to first do using OSQP

[shashins]

I did that first

[shashins]

I tried completely removing OSQP package an tried reinstalling it. I am still following error message:

Do you have cmake installed ? What happens if you do $ cmake ?

[shashins]

There was problem with the cmake version on Redhat machine. Needed 3.2 or higher version. I am able to upgrade the cmake version using https://www.heliocastro.info/?p=238. OSQP is working fine now. Thanks

[blegat]

Glad to read that you resolved the issue !

[mfalt]

The lack of cmake on some computers can be quite a problem.
While teaching a course using another package with OSQP as a dependency, a lot of computers had build errors.
I'm guessing its not possible to force cmake installation during the build?
Is there at least a way to test if cmake is installed before trying to compile?
When compilation fails, even after installing cmake, it is nessesary remove OSQP and garbage collect build files before trying to build again. If nothing else, it would be nice with some instructions in the error message on how to (re)build after failure.

Note: The errors I encountered seemed to be mostly on Ubuntu 18.04

[bstellato]

On Mac and Linux we are directly installing the precompiled libraries which do not require cmake. However, it seems that the Julia ecosystem prefers packages compilation on Linux. That's why your errors appear mostly on uUbuntu. We could add more guidelines about that in the Julia installation or use directly the precompiled library on Linux. What do you think @blegat @tkoolen ?

[mfalt]

Would it be possible to fall back on binaries if the build fail? (I haven't used BinDeps so I'm not sure what the limitations are)

[mlubin]

it seems that the Julia ecosystem prefers packages compilation on Linux

That's no longer true. The Julia ecosystem now prefers BinaryBuilder packages on all platforms. See Cbc as an example.

I haven't used BinDeps so I'm not sure what the limitations are.

BinDeps is deprecated.

[bstellato]

Ooops ok I guess we should switch to that one and use the precompiled libraries. I will open an issue.

[bstellato]

@mfalt this is fixed in release 0.5.2.
