此测试是否为编写更全面的构建模块做准备。但是我需要先掌握基础知识。渴望: -将所有“目标文件”输出构建到输出文件夹 -将它们链接到可分发的“ wasm”二进制文件中,并格式化html页面 并将它们输出到“ dist”文件夹。
我查看了以下手册:
https://kripken.github.io/emscripten-site/docs/tools_reference/emcc.html
它不像人们想要的那样直观或明确地拼写出来。 下面是我当前的简单测试版本。
#!/bin/bash
# set emscripten toolchain paths in this shell
source "${HOME}/emsdk/emsdk_env.sh" --build=Release
BuildDir="./build" # root of output dir for built files
SrcDir="./src" # a source code directory
ObjDir="${BuildDir}/obj" # where intermediate "object" files are output to.
IncludeDir="./include" # an include directory
# start clean for this test
rm -fr "${BuildDir}"
mkdir -p "${ObjDir}" # also re-creates BuildDir
# compile source code out to ObjDir
emcc --default-obj-ext .bc -o "${ObjDir}/" -I "${IncludeDir}" \
"${SrcDir}/hello.cpp" "${SrcDir}/TestClass.cpp"`
运行上述命令会给我带来错误,但如果只有一个源文件,则可以使用。
Is a directory
Traceback (most recent call last):
File "/home/peterk/emsdk/emscripten/incoming/emcc.py", line 3107, in <module>
...
status 1

下面的方法有效,但是将所有输出文件放在src /文件夹中,并为它们分配.o后缀而不是.bc后缀:它还在目录中输出.out.js和.out.wasm文件脚本从中运行。我想抑制一下,直到最后的“链接”阶段将几个编译结果在单独的步骤中链接在一起。
emcc --default-obj-ext .bc -I "${IncludeDir}" \
"${SrcDir}/hello.cpp" "${SrcDir}/TestClass.cpp"`
答案 0 :(得分:0)
好-可以正常运行,因为makefile可以一次编译一个。
#!/bin/bash
source "${HOME}/emsdk/emsdk_env.sh" --build=Release # set emscripten toolchain paths in this shell
BuildDir="./build" # root of output dir for built files
SrcDir="./src" # a source code directory
ObjDir="${BuildDir}/obj" # where intermediate "object" files are output to.
IncludeDir="./include" # an include directory
DistDir="./build/dist" # distribution "binary" output dir
# start clean for this test
rm -fr "${BuildDir}"
# compile source code out to ObjDir
mkdir -p "${ObjDir}"
objFiles=""
for srcFile in "${SrcDir}"/*.cpp; do
objFile="${ObjDir}/$(basename "$srcFile").bc"
emcc -o "${objFile}" -I "${IncludeDir}" "${srcFile}"
objFiles+="${objFile} " # save list of objFiles for link.
done
# link object files into binary runtime in DistDir
mkdir -p "${DistDir}"
emcc -s WASM=1 ${objFiles} -o "${DistDir}/hello.html"
# expose to browser to test
cd "${DistDir}"
python -c 'import SimpleHTTPServer; SimpleHTTPServer.test()'
