Hello,
I'm using Boost.Test.
When I define BOOST_AUTO_TEST_SUITE, I got a compile error
'redefinition of
boost::unit_test::ut_detail::auto_test_unit_registrar' if the all
following conditions are satisfied:
1. The test suite names are the same.
2. BOOST_AUTO_TEST_SUITE are defined in different files.
3. The files are included by one file.
4. BOOST_AUTO_TEST_SUITE are defined at the same line number.
For example,
main.cpp
#define BOOST_TEST_MODULE test
#include
#include "one.ipp"
#include "two.ipp"
one.ipp
BOOST_AUTO_TEST_SUITE(a)
BOOST_AUTO_TEST_CASE(tc1) {
}
BOOST_AUTO_TEST_SUITE_END()
two.ipp
BOOST_AUTO_TEST_SUITE(a)
BOOST_AUTO_TEST_CASE(tc2) {
}
BOOST_AUTO_TEST_SUITE_END()
Here is a live demo:

If I insert a line the top of two.ipp, no errors are occurred.

According to the following document
http://www.boost.org/doc/libs/1_63_0/libs/test/doc/html/boost_test/tests_org...
"The same test suite can be restarted multiple times inside the same
test file or in a different test files."
The compile error is caused by the following line:
https://github.com/boostorg/test/blob/develop/include/boost/test/unit_test_s...
If I replace
BOOST_JOIN( BOOST_JOIN( test_name, _registrar ), __LINE__ ) \
with
BOOST_JOIN( BOOST_JOIN( test_name, _registrar ), __COUNTER__ ) \
, then the error is disappeared.
However, __COUNTER__ is not portable.
I know that I can compile one.ipp and two.ipp separately, but I also
want to have the option that include them from one file.
Is there any good way to solve the error?
Thanks,
Takatoshi Kondo
