cout causing dev-install error

[honno]

Running pip install -e . on the root of master fails, seemingly due to the uses of cout in

vaex/packages/vaex-core/src/superstring.hpp

Lines 398 to 402 in 6600a25

	std::cout << " >> count " << count << std::endl;
	for (size_t j = 0; j < count; j++) {
	int64_t start = indices2[substart + j * 2];
	int64_t end = indices2[substart + j * 2 + 1];
	std::cout << " item " << j << " from " << start << " to " << end << std::endl;

causing

error: ‘cout’ is not a member of ‘std’

Mind I'm very ignorant on C 😅 I played around with modifying the includes of superstring.hpp i.e. #include <iostream>, but I ended up introducing new bugs heh. I have been following the installation instructions here, inc. installing pcre in my conda environment, and (recursively) pulling submodules. I get the same errors for make install, pip install -e .[dev], python setup.py develop, and pip install ..

Anything I should try? Any specific information I can give? Thanks in advance!

Possibly useful info
