Peter (and Jűrgen) I am seeing this same error when compiling on macOS 15 Sequoia on Apple Silicon with XCode 16.1 command line tools and using the default ./configure options (that is, no options at all).
I normally compile GNU APL with non-default options. The one that standsout to me (and I did this to try and match the behavior of the GNU C++ compiler on current versions of Linux_ was to bump the standard being used by the compiler to g++17. With this configuration, I do not see the compiler errors that Peter is seeing. Some investigation shows that the man page for c++ on my Mac says that default C++ standard use by the compiler is gnu++98. So, I re-ran the configure with ./configure CXXFLAGS="-O2 --std=gnu++11" to select a more modern C++ stamdard. the compilation runs successfully. Verifying what was said by the man page, I ran the following: echo '' | g++ -xc++ -E -dM - | grep cplusplus My system returns: x@y trunk % echo '' | g++ -xc++ -E -dM - | grep cplusplus #define __cplusplus 199711L which indicates thet the default C++ standard being used by the compiler pre-dates c++11 - confirming what the man page said.. Running the following to select a more modern C++ standard: x@y trunk % echo '' | g++ -xc++ -E -dM -std=c++11 - | grep cplusplus #define __cplusplus 201103L indicates that the language standard being used is C++11. So in my mind the problem is either a consruct being used by the new source code that's not acceptable to the earler C++ standard, or the Apple compiler is being really picky about that syntax in the earlier standard. I think I've got a High Sierra VM hanging around that I might be able to install the XCode command line tools on so I can test to see if gnu++11 is a supported standards option. If that's the case, I'll download the latest GNU APL SVN and see if it compiles successfully. I'll do that tomorrow for you. - paul > On Dec 1, 2024, at 2:03 PM, Peter Teeson <ptee...@me.com> wrote: > > In file included from ./../Workspace.hh:34: > ./../Quad_MX.hh:99:31: error: a space is required between consecutive right > angle brackets (use '> >') > vector<complex<double>> *vals; > ^~ > > > > ./../Quad_MX.hh:114:31: error: a space is required between consecutive right > angle brackets (use '> >') > static vector<complex<double>> getCross(Matrix * mtx); > ^~ > > > > ./../Quad_MX.hh:120:57: error: a space is required between consecutive right > angle brackets (use '> >') > static complex<double> magnitude(vector<complex<double>> &v); > ^~ > > > > ./../Quad_MX.hh:52:47: error: a space is required between consecutive right > angle brackets (use '> >') > vals = new vector<complex<double>>(r * c); > ^~ > > > > > >
