Question

我正在为嵌入式设备创建一个虚拟机（VM），它通过编译字节码来运行C和Java代码。现在我正在尝试自动编译和刷新C应用程序（Java已经可以工作）。

一个重要的手动部分是获取.c文件并将其转换为VM理解的格式。目前，它的工作原理如下：

启动Docker容器，同时将其指向.c文件所在的位置并给自己bash

〜$ docker run -i -v / home / git / bytecode_manipulation：/ c_files -t lljvm_work / bin / bash
使用容器配置的lljvm-cc工具转换.c文件，同时生成jasmin文件（转换为字节码的中间件）

docker_container $ lljvm-cc test_c_srv.c -o test_c_srv -g3
退出docker容器并运行python脚本，将.j jasmin文件转换为.uj jasmin文件，将.uj文件转换为.class文件并将其放入一个好文件夹

〜$ ./script_j_to_uj.py test_c_srv.j test_srv.uj

我想在Makefile中自动执行此操作。目前，我在makefile中有一个配方，它为Java应用程序生成.class文件，然后挖掘所有.class文件（来自C或Java应用程序）。将它们进一步处理成.raw_ujc文件并生成一个列表。理想情况下，这也会为C应用程序生成.class文件。食谱：

jre_filelist:
    CLASSPATH=$(SELF)/default_runtime/real:$(SELF)/default_runtime/fake:$(SELF)/default_runtime/fake/uj \
        javac $(SELF)/default_runtime/real/java/lang/*.java  $(SELF)/default_runtime/UJSrv.java 
    find $(SELF)/ -iname "Exception.class" -type f > $(SELF)/files #First call is overwriting
    find $(SELF)/ -iname "Runnable.class" -type f >> $(SELF)/files
    find $(SELF)/ -iname "String.class" -type f >> $(SELF)/files
    find $(SELF)/ -iname "StringBuilder.class" -type f >> $(SELF)/files
    find $(SELF)/ -iname "Thread.class" -type f >> $(SELF)/files
    find $(SELF)/ -iname "Throwable.class" -type f >> $(SELF)/files
    find $(SELF)/ -iname "UJSrv.class" -type f >> $(SELF)/files
    $(info findstring C in $(LANG) is $(findstring C, $(LANG)))
ifeq ($(findstring C, $(LANG)),C) # include C runtime
    CLASSPATH=$(SELF)/default_runtime/real:$(SELF)/default_runtime/fake:$(SELF)/default_runtime/fake/uj:$(SELF)/lljvm \
        javac $(SELF)/lljvm/runtime/*.java
    CLASSPATH=$(SELF)/default_runtime/real:$(SELF)/default_runtime/fake:$(SELF)/default_runtime/fake/uj:$(SELF)/lljvm \
        javac $(SELF)/lljvm/lib/*.java
    find $(SELF)/lljvm/runtime -iname "*.class" -type f >> $(SELF)/files
    find $(SELF)/lljvm/lib -iname "*.class" -type f >> $(SELF)/files    
    $(foreach SRV, $(SRVS_C), \
        find  $(UJ_DIR)/services/c/ -iname "$(SRV).class" -type f | xargs realpath >> $(SELF)/files && \
    ) true  
endif
    $(foreach SRV, $(SRVS_JAVA), \
        CLASSPATH=$(SELF)/default_runtime javac $(UJ_DIR)/services/java/$(SRV).java && \
        find $(UJ_DIR)/services/java/ -iname "$(SRV).class" -type f | xargs realpath >> $(SELF)/files && \
    ) true
    @while read -r file; do \
        $(CMD) "$$file" >/dev/null; \
    done < $(SELF)/files;
    rm -f $(SELF)/files && rm -f ../filelist.txt
    find $(SELF)/default_runtime/ -iname "*.raw_ujc" -type f > ../filelist.txt
ifeq ($(findstring C, $(LANG)),C) # include C runtime
    find $(SELF)/lljvm/ -iname "*.raw_ujc" -type f >> ../filelist.txt
endif   
    $(foreach SRV, $(SRVS_C), \
        find  $(UJ_DIR)/services/c/ -iname "$(SRV).raw_ujc" -type f | xargs realpath >> ../filelist.txt && \
    ) true
    $(foreach SRV, $(SRVS_JAVA), \
        find  $(UJ_DIR)/services/java/ -iname "$(SRV).raw_ujc" -type f | xargs realpath >> ../filelist.txt && \
    ) true

所以做这些步骤有点困难，我希望得到建议。主要是引导容器或预先启动容器并为其提供命令。

在摆弄后，我做了我想要的事情：

compile_c:
    docker run -v $(UJ_DIR)/services/c/:/c_files -w /c_files -it lljvm_work \
            /bin/bash -c '../usr/local/lib/lljvm/lljvm-cc $(SRV).c -l_c_support -o $(SRV) -g3'
    sudo python   script_j_to_uj.py $(UJ_DIR)/services/c/$(SRV).j $(UJ_DIR)/services/c/$(SRV).uj
    rm -f $(UJ_DIR)/services/c/$(SRV)

在配方中，使用如下：

jre_filelist:
    CLASSPATH=$(SELF)/default_runtime/real:$(SELF)/default_runtime/fake:$(SELF)/default_runtime/fake/uj \
        javac $(SELF)/default_runtime/real/java/lang/*.java  $(SELF)/default_runtime/UJSrv.java 
    find $(SELF)/ -iname "Exception.class" -type f > $(SELF)/files #First call is overwriting
    find $(SELF)/ -iname "Runnable.class" -type f >> $(SELF)/files
    find $(SELF)/ -iname "String.class" -type f >> $(SELF)/files
    find $(SELF)/ -iname "StringBuilder.class" -type f >> $(SELF)/files
    find $(SELF)/ -iname "Thread.class" -type f >> $(SELF)/files
    find $(SELF)/ -iname "Throwable.class" -type f >> $(SELF)/files
    find $(SELF)/ -iname "UJSrv.class" -type f >> $(SELF)/files
    $(info findstring C in $(LANG) is $(findstring C, $(LANG)))
ifeq ($(findstring C, $(LANG)),C) # include C runtime
    CLASSPATH=$(SELF)/default_runtime/real:$(SELF)/default_runtime/fake:$(SELF)/default_runtime/fake/uj:$(SELF)/lljvm \
        javac $(SELF)/lljvm/runtime/*.java
    CLASSPATH=$(SELF)/default_runtime/real:$(SELF)/default_runtime/fake:$(SELF)/default_runtime/fake/uj:$(SELF)/lljvm \
        javac $(SELF)/lljvm/lib/*.java
#   find $(SELF)/default_runtime/real/java/lang/lljvm/util -iname "*.class" -type f >> $(SELF)/files
#   find $(SELF)/default_runtime/real//java/lang/lljvm/tools -iname "*.class" -type f >> $(SELF)/files
#   find $(SELF)/default_runtime/real//java/lang/lljvm/tools/info -iname "*.class" -type f >> $(SELF)/files
#   find $(SELF)/default_runtime/real//java/lang/lljvm/tools/ld -iname "*.class" -type f >> $(SELF)/files
    find $(SELF)/lljvm/runtime -iname "*.class" -type f >> $(SELF)/files
#   find $(SELF)/default_runtime/real//java/lang/lljvm/io -iname "*.class" -type f >> $(SELF)/files
    find $(SELF)/lljvm/lib -iname "*.class" -type f >> $(SELF)/files    
    $(foreach SRV, $(SRVS_C), \
        make compile_c SRV=$(SRV) && \
        find  $(UJ_DIR)/services/c/ -iname "$(SRV).class" -type f | xargs realpath >> $(SELF)/files && \
    ) true  
endif
    $(foreach SRV, $(SRVS_JAVA), \
        CLASSPATH=$(SELF)/default_runtime javac $(UJ_DIR)/services/java/$(SRV).java && \
        find $(UJ_DIR)/services/java/ -iname "$(SRV).class" -type f | xargs realpath >> $(SELF)/files && \
    ) true
    @while read -r file; do \
        $(CMD) "$$file" >/dev/null; \
    done < $(SELF)/files;
    rm -f $(SELF)/files && rm -f ../filelist.txt
    find $(SELF)/default_runtime/ -iname "*.raw_ujc" -type f > ../filelist.txt
ifeq ($(findstring C, $(LANG)),C) # include C runtime
    find $(SELF)/lljvm/ -iname "*.raw_ujc" -type f >> ../filelist.txt
endif   
    $(foreach SRV, $(SRVS_C), \
        find  $(UJ_DIR)/services/c/ -iname "$(SRV).raw_ujc" -type f | xargs realpath >> ../filelist.txt && \
    ) true
    $(foreach SRV, $(SRVS_JAVA), \
        find  $(UJ_DIR)/services/java/ -iname "$(SRV).raw_ujc" -type f | xargs realpath >> ../filelist.txt && \
    ) true

GNU Make：启动Docker容器，使其执行命令，退出容器，执行脚本
