Compilation issue at step #4

[wzball]

Hi, thanks for the project.

I have an Oracle Linux 7.5 system that I am trying to compile this code on. After installing dependencies and patching the code, I executed the compiling steps. I get an error that I can't get passed;

Error output

/root/.nimble/pkgs/qt5_qtsql-1.1.1/qt5_qtsql/src/immutablecstring.nim(31, 37) Error: undeclared identifier: 'expr'
     Error: Execution failed with exit code 1
        ... Command: "/usr/local/nim/bin/nim" cpp --noNimblePath -d:NimblePkgVersion=1.0.0 --path:"/root/.nimble/pkgs/qt5_qtsql-1.1.1" --path:"/root/.nimble/pkgs/microasynchttpserver-0.10.2" --path:"/root/.nimble/pkgs/picohttpparser-0.10.0" "--out:bin/influx_mysql"  "influx_mysql/src/influx_mysql"

Step 1

# pwd
/usr/local/influx-mysql
# git submodule update --init
#

Step 2

# nimble install -d

   Warning: Package 'picohttpparser' has an incorrect structure. The top level of the package source directory should contain at most one module, named 'picohttpparser.nim', but a file named 'picohttpparser_api.nim' was found. This will be an error in the future.
      Hint: If this is the primary source file in the package, rename it to 'picohttpparser.nim'. If it's a source file required by the main module, or if it is one of several modules exposed by 'picohttpparser', then move it into a 'picohttpparser/' subdirectory. If it's a test file or otherwise not required to build the the package 'picohttpparser.nim', prevent its installation by adding `skipFiles = @["picohttpparser_api.nim"]` to the .nimble file. See https://github.com/nim-lang/nimble#libraries for more info.
