Can't compile release_003_005_002

[andrersimoes]

Gentlemen.

I could not compile release 003_005_002 under Slackware 14.2.
I'm using gcc 7.2.0

A snippet of my compiler output where the problem occurs:

[ 98%] Built target uhd_cal_tx_iq_balance /tmp/SBo/UHD-Mirror-release_003_005_002/host/utils/usrp_n2xx_simple_net_burner.cpp: In function ‘bool does_image_exist(std::string)’: /tmp/SBo/UHD-Mirror-release_003_005_002/host/utils/usrp_n2xx_simple_net_burner.cpp:67:12: error: cannot convert ‘std::ifstream {aka std::basic_ifstream<char>}’ to ‘bool’ in return return ifile;
In my case i've locally added

std::ifstream ifile;
ifile.open( (char*) image_filepath.c_str() );
return ! ifile.fail();

Hope it helps
