No rule to make target '/home/dan/work/rnd/zipcpu/sw/install/cross-tools/zip/lib/libg.a', needed by 'hello'.

Hi, I'm trying to build zbasic as per http://zipcpu.com/zipcpu/2018/01/31/cpu-build.html however I get the above in sw/build.

Some digging shows the INSTALLD path in sw/build/Makefile is hard coded with your (I assume) path. I changed it to be INSTALLD?=.. then ran make like so.. make INSTALLD=/media/psf/Home/projects/zipcpu/sw/install

I'm not sure what the 'right' way is but this works OK :)

Yeah, I'm not quite sure what the "right" way is either. Perhaps querying the path of the current "zipcpu-gcc" and using that to indicate the path of the install directory?

How about something like:

diff --git a/sw/board/Makefile b/sw/board/Makefile
index 0eb2b8b..fe09190 100644
--- a/sw/board/Makefile
+++ b/sw/board/Makefile
@@ -60,7 +60,8 @@ LFLAGS  := -T $(LDSCRIPT) -L../zlib
 LBKRAM  := -T bkram.ld -L../zlib
 CFLAGS  := -O3 -I../zlib -I../../rtl
 LIBS    := -lc -lzbasic -lgcc
-INSTALLD=/home/dan/work/rnd/zipcpu/sw/install
+INSTALLD_ := $(cd $(dirname $(which zip-gcc))/../..; pwd)
+INSTALLD?= $(INSTALLD_)
 NLIBD=$(INSTALLD)/cross-tools/zip/lib
 ZLIBD=../zlib
 LIB=$(ZLIBD)/libzbasic.a $(NLIBD)/libg.a $(NLIBD)/libc.a

It should work for people following the tutorial without any editing and also let you override it if you want.

Let me close this issue. It's been long fixed (or at least, so I'm convinced), and I've removed all references to absolute path names from the ZBasic repository.
