Question

我已经在我的x86 32-bit linux系统上建造了4.7海合会。当我试图与国旗64号交织在一起时,我得到以下信息:

骚扰、未执行:64条轨道模式未汇编

虽然由于我的无缘分配而提供的汇编者可以与——m64相交叉。

What do I have to pass to ./configure to enable the 64bit mode in GCC? These are the options I used to build GCC 4.7:

$ /usr/local/bin/g++ -v Using built-in specs.
COLLECT_GCC=/usr/local/bin/g++
COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/i686-pc-linux-gnu/4.7.0/lto-wrapper
Target: i686-pc-linux-gnu
Configured with: ./configure --enable-multiarch --with-cloog=/usr/local/ --with-mpfr=/usr/local/ --with-ppl=/usr/local/ --verbose --enable-languages=c,c++
Thread model: posix gcc version 4.7.0 20120113 (experimental) (GCC)

EDIT:

-----------------------------------------------------------

这并不改变局势。汇编者仍然抱怨说,有64个轨道模式没有编纂成:

$ g++ -v Using built-in specs. COLLECT_GCC=g++ COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/i686-pc-linux-gnu/4.7.0/lto-wrapper Target: i686-pc-linux-gnu Configured with: ./configure --enable-multiarch --with-cloog=/usr/local/ --with-mpfr=/usr/local/ --with-ppl=/usr/local/ --verbose --enable-languages=c,c++ --enable-multilib --enable-targets=i686-pc-linux-gnu,x86_64-pc-linux-gnu Thread model: posix gcc version 4.7.0 20120113 (experimental) (GCC)

$ g++ -m64 c.cpp c.cpp:1:0: sorry, unimplemented: 64-bit mode not compiled in

Answer 1

你们既需要双用途,又需要与:

--enable-multilib

可能的话:

--enable-targets=i686-pc-linux-gnu,x86_64-pc-linux-gnu

(-m64和(或)-m32备择)。你们也需要两种像平衡一样的足迹,才能连接和管理由此产生的双手。

Answer 2

这通常意味着你重新使用错误(旧)汇编者。

新的汇编者支持m32和-m64。你们必须把PATH安排给新编者(在履带上,MinGW列车子) < 之前,里托列斯的任何老编。

3. 更新编辑的双轨平衡途径,使其达到64个轨道版本。诸如校正等其他资源也应相应改变。

Just resolved this issue. In the environment variables, remove the entries to any outdated c++ package.

In my case, I worked in Anaconda on Windows 64-bit. In anaconda, I performed conda install mingw libpython . Mingw is for c++ compiler. But I had earlier installed cygwin s mingw for c++ compilations which hadn t been updated. This is the reason for conflict. I resolved this issue by simply removing the environment variable (PATH) corresponding to these c++ packages.
I have tried almost all forums, this solution works.

如果有人需要帮助,请让我知道:

I had the same problem on windows. Despite installing codeblock 20.03 I couldn t compile my code 64 bit. I solved it by setting the compiler to x86_64-w64-mingw32-g++.exe instead of g++.exe. It was in the bin directory as g++.exe. In windows go to Settings menue and: Settings->Compiler... select the "toolchain executables" tab and and from there on it is obvious.

同样的问题。我的解决办法:

Update everything (R, Rstudio, R packages) and close Rstudio.
Uninstall Rtools and install the latest version.
Add only 2 entries under Enviroment Variables/System variables/Path:
- C:Rtoolsin
- C:Rtoolsmingw_64in (!not the 32bit version)
Path entries have to be in this order and above %SystemRootSystem32
I did NOT install in the strongly recommended default location on C:

After that open Rstudio and re-install Rcpp via console:
install.packages("Rcpp")

Test if it s working with:
Rcpp::evalCpp("2+2")

After that just switch to the Terminal in Rstudio, go into the cmdstan source folder and type make build .
--- CmdStan v2.19.1 built ---
Done!
