Syntax error in sunwait.cpp

[goverp]

Hi, thanks for this very useful piece of code that I've used for some time. I've just cloned it onto my new Raspberry Pi and tried to run "make", and it fails in compilation in sunwait.cpp at lines 707 on, where the if statement has incorrect bracketing. I think it should be:

else if   (!strcmp (arg, "debug")           ||
              !strcmp (arg, "--debug")      ||
              !strcmp (arg, "--verbose")    ||
              !strcmp (arg, "-v"))           pRun->debug = ONOFF_ON;

If I trusted my C++ and git skills more, I'd send a pull request.

Same issue when building as OpenWRT package:

Overcomed with exact version setting in Makefile:

PKG_SOURCE_VERSION:=102cb417ecbb7a3757ba9ee4b94d6db3225124c4

Trying to compile on RASPI Bullseye.

Excuse my ignorance, but I have placed the line cited above "PKG_SOURCE_VERSION:=102cb417ecbb7a3757ba9ee4b94d6db3225124c4" after the line beginning "LDFLAGS..." in makefile and I get the same error as reported by "sebma".

@likemotion using the PKG_SOURCE_VERSION is valid only for OpenWRT specific makefile.

You could probably try clone the repository and then switch version:

git clone https://github.com/risacher/sunwait.git
cd sunwait
git checkout 102cb417ecbb7a3757ba9ee4b94d6db3225124c4
make

Thanks very much Peter for your help; sorry for the delay in following-up - its now working and can now get on with the next stage.

Fab service!

Cheers,

Mike

FYI here's the output I got:

@likemotion using the PKG_SOURCE_VERSION is valid only for OpenWRT specific makefile .

You could probably try clone the repository and then switch version: git clone https://github.com/risacher/sunwait.git cd sunwait git checkout 102cb417ecbb7a3757ba9ee4b94d6db3225124c4 make

Hi @likemotion

happy to hear that. This is only warnings from compiler.

You can run sunwait from current directory:

pi@raspberrypi:/tmp/sunwait $ ./sunwait help
