Bazel: set runtime environment variable and configuration file location for cc_binary/cc_test

I am trying to use odbc++ in a C++ application on linux. The following build file is used to include the library as an external dependency

licenses(["notice"])
cc_library(
    name = "lib",
    srcs=["lib/libodbc.so","lib64/libodbc++-mt.so"],
    hdrs=glob(["include/**/*.h","include/*.h"]),
    includes = ["include"],
    visibility = ["//visibility:public"],
    linkstatic = 1,
    data = [ "odbc.ini", "odbcinst.ini" ]
)

My bash profile has ODBCINI and OBCDINST set so running the binary directly from command line is fine. However, the environment variable ODBCINI and ODBCINST are not set when running bazel test.

Is there anyway to include the configuration files and set the run time environment variables to them?

Solution

  • You can set environment variables for test execution in bazel with the --test_env flag. The documentation is here.

    For example, bazel build --test_env ODBCINI=foo //my:test
