配置：錯誤：C編譯器無法在mac os終端中創建可執行文件

Question

我試圖在iOS 4.2中構建libCURL，我在終端中執行一些步驟。 的步驟是：

1. cd curl-7.21.2
2. export CC=/Developer\ 4.2/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-gcc-4.0.1
3. export CFLAGS="-isysroot /Developer\ 4.2/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk"
4. export LDFLAGS="-isysroot /Developer\ 4.2/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk -Wl,-syslibroot /Developer\ 4.2/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk"
5. export CPP=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/cpp
6. ./configure --disable-shared --without-ssl --without-libssh2 --without-ca-bundle --without-ldap --disable-ldap --host=arm-apple-darwin10

但自來水後進入終端告訴我這些警告和錯誤：

這是的config.log：

This file contains any messages produced by compilers while 
running configure, to aid debugging if configure makes a mistake. 

It was created by curl configure -, which was 
generated by GNU Autoconf 2.68. Invocation command line was 

    $ ./configure --disable-shared --without-ssl --without-libssh2 --without-ca-bundle --without-ldap --disable-ldap --host=arm-apple-darwin10

上Bavarious意見的基礎上，我已經改變所有的命令中的每一步，這些是更新：

1. export CC='\"/Developer 4.2/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-gcc-4.0.1\">
2. export CFLAGS="-isysroot \"/Developer 4.2/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk\""
3. export LDFLAGS="-isysroot \"/Developer 4.2/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk -Wl,-syslibroot \"/Developer 4.2/Platforms/icleaPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk"""
4. export CPP='\"/Developer 4.2/Platforms/iPhoneOS.platform/Developer/usr/bin/cpp">
5. ./configure --disable-shared --without-ssl --without-libssh2 --without-ca-bundle --without-ldap --disable-ldap --host=arm-apple-darwin10

，但它使終端沒有執行命令。

我不明白它是什麼，有人可以告訴我嗎？

謝謝

Answer 1

如果你是獅子嘗試與標籤安裝：--with-gcc=clang

運行rvm requirements更詳細地解釋了這一點：

Xcode 4.2: 
* is only supported by ruby 1.9.3+ using command line flag: --with-gcc=clang 
* it breaks gems with native extensions, especially DB drivers. 

Xcode 4.2 users - please be warned - 
in case of any compilation issues 
* downgrade to Xcode 4.1 
* or install osx-gcc-installer 
and reinstall your rubies. 

Answer 2

的問題是在路徑名的空間。更重要的是，除非你刪除它們，否則不是一個簡單的解決方法。

麻煩的是在日誌文件 - 它只是顯示它的中部附近...

爲了獲得與空間的路徑工作，你必須要能夠保證每當使用CC時，路徑都用雙引號括起來。您還需要限制CFLAGS值，以便路徑不會分裂，但-isysroot與通向-isysroot的路徑是分開的。

如果你想冒險，你可以嘗試使用：

export CC="\"/Developer 4.2/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-gcc-4.0.1\"" 
export CFLAGS="-isysroot \"/Developer 4.2/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk\"" 

有一個外部的機會，它會工作，但我不想依賴它。基本上，它會在環境變量值的明智選擇的點上添加雙引號，希望shell能夠設法將它們保留在正確的位置。我認爲它不會起作用，但它可能值得一試。

我建議重新命名，你有沒有空間安裝軟件的路徑，也許是因爲：

/Developer-4.2/Platforms/... 

（我有一個目錄$HOME/External Source Repositories簡單地說，與地區爲git和svn和hg（水銀）副本外部源代碼庫，包括所提到的VCS，雖然名稱中包含空格，但VCS仍然可用，但下載的代碼庫（包括VCS自己的構建系統）的構建過程不是（包括git，IIRC）。改爲$HOME/External-Source-Repositories）。
