我正在尝试将Boost编译为共享库，并使它们成为我的跨平台 CMake项目的依赖项。
为此，我为win32，x64和linux编译了boost，它们的boost文件夹结构如下：
- boost_1_69_0/
- boost/
- stage/
- win32
- lib
- x64
- lib
- linux
- lib
然后我在做
set(BOOST_INCLUDEDIR ${CMAKE_CURRENT_SOURCE_DIR}/../external/boost_1_69_0)
set(BOOST_LIBRARYDIR ${CMAKE_CURRENT_SOURCE_DIR}/../external/boost_1_69_0/stage/win32)
find_package(Boost REQUIRED COMPONENTS filesystem)
并得到：
CMake Error at C:/Program Files/CMake/share/cmake-3.13/Modules/FindBoost.cmake:2100 (message):
Unable to find the requested Boost libraries.
Boost version: 1.69.0
Boost include path: C:/bla/SW/cmake-template/external/boost_1_69_0
Could not find the following Boost libraries:
boost_filesystem
那是个错误吗？
如果我将lib文件夹从win32内部移到其父目录，即：
- boost_1_69_0/
- boost/
- stage/
- lib
这是boost的b2构建东西的默认方式，然后一切正常。但是后来我无法为不同的平台使用不同的boost二进制文件。
编辑：
使用set(Boost_DEBUG ON)，我发现我的项目是在使用v140的情况下使用Visual Studio v141工具集编译的，因此FindBoost在寻找boost_filesystem-vc140-mt-x64-1_69而不是boost_filesystem-vc140-mt-x64-1_69
我想问题已经转移到找到一种方法来强制搜索v141或（更好）使用--layout=system，并找到一种方法使其强制寻找boost_filesystem。有办法吗？
答案 0 :(得分：1)
这里的问题是CMake搜索与特定命名方案匹配的boost库。您的库与此不同，因为文件名中编码了一些选项。您有两种选择：
module FSM_TB;
reg clk,left, right, reset;
wire LA,LB,LC,RA,RB,RC;
FSM dut(clk, reset, left, right, LA, LB, LC, RA, RB, RC);
//apply inputs
initial begin
reset = 0; left = 1; right = 0; #30;
reset = 1;#30;
end
//generate clock
always begin
clk = 0; #5;
clk = 1; #5;
end
endmodule
可执行文件时带有module FSM(
input clk,
input reset,
input left,
input right,
output LA,
output LB,
output LC,
output RA,
output RB,
output RC
);
reg[2:0] state = 3'b000;
reg [2:0] nextstate;
reg r ;
parameter S0 = 3'b000;
parameter S1 = 3'b100;
parameter S2 = 3'b110;
parameter S3 = 3'b111;
//state register
always @ (posedge clk, posedge reset)
if(reset)
begin
state <= S0;
r = 0;
end else begin // if !reset
if(left) r = 0;
if(right) r = 1;
state <= nextstate;
end
//next state logic
always @ (*)
case(state)
S0: if(left^right) //if left xor right is 1, state is going to change
nextstate = S1;
else nextstate = S0;
S1: nextstate = S2;
S2: nextstate = S3;
S3: nextstate = S0;
default: nextstate = S0;
endcase
//output logic
assign LC = (r== 0) & (state==S3);
assign LB = (r== 0) & ((state==S3)|(state == S2));
assign LA = (r== 0) & ((state==S3)|(state == S2)|(state == S1));
assign RC = (r == 1) &(state==S3);
assign RB = (r == 1) &((state==S3)|(state == S2));
assign RA = (r == 1) &((state==S3)|(state == S2)|(state == S1));
endmodule
标志。这将创建具有标准名称（如pandas和import pandas as pd
cars=pd.read_csv("./cars.csv")
prices=pd.read_csv("./price.csv")
### iterate over the price changes as rows
for i,row in prices.iterrows():
### find where cars["tittle2"]==row["ori_price1"]
# and update column ['tittle2'] to row["new_price2"]
cars.loc[cars["tittle2"]==row["ori_price1"], ['tittle2']] = row["new_price2"]
cars.to_csv("cars_updated.csv",index=False)
之类的库文件。.grid {
