Hi Russ – On OpenBSD, clang has been the default compiler for many years. I routinely build APL trunk on OpenBSD, and never had any problems so long as I add -std=gnu++11 to CXXFLAGS. I just rebuilt APL from a clean SVN checkout and it built without issues.
I am using clang-16.0.6. Not sure what version Termux uses these days. ~Brian -- Brian Robert Callahan, Ph.D., CISSP, CCSP, SSCP, CC Graduate Program Director, ITWS@RPI Director, Rensselaer Cybersecurity Collaboratory Office: Lally 304 From: bug-apl-bounces+callab5=rpi....@gnu.org <bug-apl-bounces+callab5=rpi....@gnu.org> On Behalf Of Russtopia Sent: Monday, October 2, 2023 8:08 PM To: bug-apl@gnu.org Subject: [EXTERNAL]Building GNU APL with clang CAUTION: This email originated from outside of the organization.

I would rather not, but in this case I am trying to re-build GNU APL in Termux on my newer Android phone, and Termux decided some time ago to remove gcc entirely from its packages, in preference to clang. :( I am not up to date at all on modern C++, but this conversation on Stackoverflow suggests that auto_ptr is considered deprecated in newer C++ standards: https://stackoverflow.com/questions/69116001/how-do-i-re-enable-c17-removed-features-in-clang libtool: compile: g++ -DHAVE_CONFIG_H -I. -I../.. -Wno-deprecated-declarations -g -O2 -I /data/data/com.termux/files/home/gnuapl/trunk -c Listener.cc -o Listener.o >/dev/null 2>&1 network.cc:37:10: error: no member named 'auto_ptr' in namespace 'std' std::auto_ptr<NetworkConnection> connection( (NetworkConnection *)arg ); ~~~~~^ network.cc:37:19: error: 'NetworkConnection' does not refer to a value std::auto_ptr<NetworkConnection> connection( (NetworkConnection *)arg ); ^ Adding -std=c++11 to src/emacs-mode/Makefile CXXFLAGS got me past the auto_ptr issues, but then I hit issues with 'typeof()' in LineInput.cc: g++ -DHAVE_CONFIG_H -I. -I.. -Wall -I sql -I /data/data/com.termux/files/home/gnuapl/trunk -std=c++11 -g -O2 -I /data/data/com.termux/files/home/gnuapl/trunk -MT apl-Missing_Libraries.o -MD -MP -MF .deps/apl-Missing_Libraries.Tpo -c -o apl-Missing_Libraries.o `test -f 'Missing_Libraries.cc' || echo './'`Missing_Libraries.cc LApack.cc:1784:37: error: unknown type name 'typeof'; did you mean 'typedef'? tau = reinterpret_cast<typeof(tau)> (work); ^~~~~~ typedef LApack.cc:1784:43: error: expected a type tau = reinterpret_cast<typeof(tau)> (work); ^ LApack.cc:1784:37: error: type name does not allow storage class to be specified tau = reinterpret_cast<typeof(tau)> (work); ^ Has anyone managed to build and successfully run GNU APL with clang? -Russ
