Question

我在新安装的操作系统Ubuntu 14.04.1上从源代码构建Julia。

git clone https://github.com/JuliaLang/julia.git 
make -C deps getall
make -j 12

构建openssl依赖项之一的libgit2时发生Julia错误。

错误消息是：

Answer 1

您需要根据Julia libssl-dev：

安装README.md

Required build tools and external libraries

openssl - 在Linux上的libgit2中支持HTTPS，需要通过 apt-get install libssl-dev 或yum install openssl-devel进行安装。

因此，为了在Ubuntu中安装它，请在终端中发出以下命令：

sudo apt-get install libssl-dev

之后，您可能会再次尝试重新编译Julia。

        font_size: '20dp'
        size_hint_y: None

看起来Julia配置错误。

根据您的评论“我已经安装了libssl-dev并且还从源手动构建了另一个版本openssl ....”，您应该在某处看到/usr/bin/cc -DCLAR_FIXTURE_PATH=\"/home/guo/Github/libgit2/tests/resources/\" -DCLAR_RESOURCES=\"\" -DCLAR_TMPDIR=\"libgit2_tests\" -DGIT_ARCH_64 -DGIT_CURL -DGIT_OPENSSL -DGIT_THREADS -DGIT_USE_NSEC -DGIT_USE_STAT_MTIM -DHAVE_FUTIMENS -DHAVE_QSORT_R -DOPENSSL_SHA1 -D_FILE_OFFSET_BITS=64 -I/home/guo/Github/libgit2/src -I/home/guo/Github/libgit2/include -I/usr/local/include -I/home/guo/Github/libgit2/deps/http-parser -I/home/guo/Github/libgit2/tests -D_GNU_SOURCE -Wall -Wextra -fvisibility=hidden -fPIC -Wno-missing-field-initializers -Wstrict-aliasing=2 -Wstrict-prototypes -Wdeclaration-after-statement -Wno-unused-function -g -o CMakeFiles/libgit2_clar.dir/src/openssl_stream.c.o -c /home/guo/Github/libgit2/src/openssl_stream.c /home/guo/Github/libgit2/src/openssl_stream.c: In function ‘bio_create’: /home/guo/Github/libgit2/src/openssl_stream.c:159:3: error: dereferencing pointer to incomplete type b->init = 1; ...选项像-I这样的东西。如果在-I /usr/local/ssl/include安装了OpenSSL，则标头位置为/usr/local/ssl，库位置为/usr/local/ssl/include。

您应该在/usr/local/ssl/lib中包含-Wl,-rpath,/usr/local/ssl/lib，以确保运行时链接能够获取正确的OpenSSL库。或者，您可能必须使用CFLAGS（但通常更容易使用RPATH）。

Julia对配置OpenSSL（除了需要的配置）没什么好说的：

LD_LIBRARY_PATH

如果朱莉娅是一个表现良好的项目并且它尊敬$ cat README.md | grep -B 1 -A 1 -i ssl - **[cmake]** — needed to build `libgit2`. - **[openssl]** — needed for HTTPS support in `libgit2` on Linux, install via `apt-get install libssl-dev` or `yum install openssl-devel`. - **[pkg-config]** - needed to build libgit2 correctly, especially for proxy support -- [libunwind]: http://www.nongnu.org/libunwind [openssl]: https://www.openssl.org [libssh2]: https://www.libssh2.org，那么这就是你应该做的全部：

CFLAGS

如果有任何C ++组件，那么您将需要使用：

$ export CFLAGS="-I/usr/local/ssl/include -L/usr/local/ssl/lib -Wl,-rpath,/usr/local/ssl/lib"
$ CFLAGS="$CFLAGS" make -C deps getall
$ CFLAGS="$CFLAGS" make VERBOSE=1

在大多数情况下，它看起来很尊重您的$ CFLAGS="$CFLAGS" CXXFLAGS="$CFLAGS" make -C deps getall $ CFLAGS="$CFLAGS" CXXFLAGS="$CFLAGS" make VERBOSE=1：

CFLAGS

我不知道其他Julia问题，例如$ CFLAGS="$CFLAGS" make VERBOSE=1 make[1]: Entering directory '/Users/jwalton/julia/deps' ... echo make -C build/openblas-12ab1804b6ebcd38b26960d65d254314d8bc33d6/ CC="clang -mmacosx-version-min=10.6 -m64" FC="gfortran -m64" RANLIB="ranlib" FFLAGS=" -O2 -fPIC" TARGET= BINARY=64 USE_THREAD=1 GEMM_MULTITHREADING_THRESHOLD=50 NUM_THREADS=16 NO_AFFINITY=1 DYNAMIC_ARCH=1 INTERFACE64=1 SYMBOLSUFFIX="64_" LIBPREFIX="libopenblas64_" OBJCONV=/Users/jwalton/julia/deps/build/objconv/objconv MAKE_NB_JOBS=0 # echo first, so we only print the error message below in a failure case make -C build/openblas-12ab1804b6ebcd38b26960d65d254314d8bc33d6/ CC=clang -mmacosx-version-min=10.6 -m64 FC=gfortran -m64 RANLIB=ranlib FFLAGS= -O2 -fPIC TARGET= BINARY=64 USE_THREAD=1 GEMM_MULTITHREADING_THRESHOLD=50 NUM_THREADS=16 NO_AFFINITY=1 DYNAMIC_ARCH=1 INTERFACE64=1 SYMBOLSUFFIX=64_ LIBPREFIX=libopenblas64_ OBJCONV=/Users/jwalton/julia/deps/build/objconv/objconv MAKE_NB_JOBS=0 make[2]: Entering directory '/Users/jwalton/julia/deps/build/openblas-12ab1804b6ebcd38b26960d65d254314d8bc33d6' make[3]: Entering directory '/Users/jwalton/julia/deps/build/openblas-12ab1804b6ebcd38b26960d65d254314d8bc33d6/interface' clang -mmacosx-version-min=10.6 -m64 -I/usr/local/ssl/include -L/usr/local/ssl/lib -Wl,-rpath,/usr/local/ssl/lib -O2 -DMAX_STACK_ALLOC=2048 -DEXPRECISION -Wall -m64 -DF_INTERFACE_GFORT -fPIC -DDYNAMIC_ARCH -DSMP_SERVER -DNO_WARMUP -DMAX_CPU_NUMBER=16 -DASMNAME=_ -DASMFNAME=__ -DNAME=_ -DCNAME= -DCHAR_NAME=\"_\" -DCHAR_CNAME=\"\" -DNO_AFFINITY -I. -O2 -DMAX_STACK_ALLOC=2048 -DEXPRECISION -Wall -m64 -DF_INTERFACE_GFORT -fPIC -DDYNAMIC_ARCH -DSMP_SERVER -DNO_WARMUP -DMAX_CPU_NUMBER=16 -DASMNAME=_saxpy -DASMFNAME=_saxpy_ -DNAME=saxpy_ -DCNAME=saxpy -DCHAR_NAME=\"saxpy_\" -DCHAR_CNAME=\"saxpy\" -DNO_AFFINITY -I.. -I. -UDOUBLE -UCOMPLEX -c axpy.c -o saxpy.o clang: warning: -Wl,-rpath,/usr/local/ssl/lib: 'linker' input unused clang: warning: argument unused during compilation: '-L/usr/local/ssl/lib' In file included from <built-in>:320: <command line>:22:9: warning: 'ASMNAME' macro redefined [-Wmacro-redefined] #define ASMNAME _saxpy ^。我猜测（这纯粹是猜测），因为我在OS X上测试它，但是它没有真正支持它（'ASMNAME' macro redefined是一个赠品，因为OS X使用Apple的{{1} }，而不是RANLIB="ranlib"）。

为BIO构建libgit2，openssl_stream.c和“错误：解除指向不完整类型的指针”
