琼斯福斯分割故障

Question

我所在的系统:

/tmp/jonesforth $ cat /etc/issue
Ubuntu 16.04.1 LTS n l

这是一个32位系统。

从附件库克隆:

git clone git://git.annexia.org/git/jonesforth.git

build goes OK:

cd jonesforth
/tmp/jonesforth $ make
gcc -m32 -nostdlib -static -Wl,-Ttext,0  -o jonesforth jonesforth.S

但是测试不通过:

/tmp/jonesforth $ make test
test_stack_trace.f ... --- .test_stack_trace.test   2016-09-17 17:44:59.488492834 -0500

启动jonesforth导致段错误:

/tmp/jonesforth $ cat jonesforth.f - | ./jonesforth 
Segmentation fault

Answer 1

从jonesforth的Makefile条目中删除-Wl,-Ttext,0:

jonesforth: jonesforth.S
    gcc -m32 -nostdlib -static $(BUILD_ID_NONE) -o $@ $<

似乎有帮助。构建成功:

/tmp/jonesforth $ touch jonesforth.S 
/tmp/jonesforth $ make
gcc -m32 -nostdlib -static  -o jonesforth jonesforth.S

测试通过:

/tmp/jonesforth $ make test
test_stack_trace.f ... ok
test_stack.f ... ok
test_comparison.f ... ok
test_assembler.f ... ok
test_exception.f ... ok
test_read_file.f ... ok
test_number.f ... ok

它启动了:

/tmp/jonesforth $ cat jonesforth.f - | ./jonesforth 
JONESFORTH VERSION 47
